c { dg-do compile } * Date: Sat, 16 Mar 1996 19:58:37 -0500 (EST) * From: Kate Hedstrom <kate@ahab.Rutgers.EDU> * To: burley@gnu.ai.mit.edu * Subject: g77 bug in assign * * I found some files in the NCAR graphics source code which used to * compile with g77 and now don't. All contain the following combination * of "save" and "assign". It fails on a Sun running SunOS 4.1.3 and a * Sun running SunOS 5.5 (slightly older g77), but compiles on an * IBM/RS6000: * C SUBROUTINE QUICK SAVE C ASSIGN 101 TO JUMP ! { dg-warning "Obsolete: ASSIGN" "" } 101 Continue C RETURN END * * Everything else in the NCAR distribution compiled, including quite a * few C routines. * * Kate * * * nemo% g77 -v -c quick.f * gcc -v -c -xf77 quick.f * Reading specs from /usr/local/lib/gcc-lib/sparc-sun-sunos4.1.3/2.7.2/specs * gcc version 2.7.2 * /usr/local/lib/gcc-lib/sparc-sun-sunos4.1.3/2.7.2/f771 quick.f -fset-g77-defaults -quiet -dumpbase quick.f -version -fversion -o /usr/tmp/cca24166.s * GNU F77 version 2.7.2 (sparc) compiled by GNU C version 2.7.1. * GNU Fortran Front End version 0.5.18-960314 compiled: Mar 16 1996 14:28:11 * gcc: Internal compiler error: program f771 got fatal signal 11 * * * nemo% gdb /usr/local/lib/gcc-lib/*/*/f771 core * GDB is free software and you are welcome to distribute copies of it * under certain conditions; type "show copying" to see the conditions. * There is absolutely no warranty for GDB; type "show warranty" for details. * GDB 4.14 (sparc-sun-sunos4.1.3), * Copyright 1995 Free Software Foundation, Inc... * Core was generated by `f771'. * Program terminated with signal 11, Segmentation fault. * Couldn't read input and local registers from core file * find_solib: Can't read pathname for load map: I/O error * * Couldn't read input and local registers from core file * #0 0x21aa4 in ffecom_sym_transform_assign_ (s=???) at f/com.c:7881 * 7881 if ((ffesymbol_save (s) || ffe_is_saveall ()) * (gdb) where * #0 0x21aa4 in ffecom_sym_transform_assign_ (s=???) at f/com.c:7881 * Error accessing memory address 0xefffefcc: Invalid argument. * (gdb) * * * ahab% g77 -v -c quick.f * gcc -v -c -xf77 quick.f * Reading specs from /usr/local/lib/gcc-lib/sparc-sun-solaris2.5/2.7.2/specs * gcc version 2.7.2 * /usr/local/lib/gcc-lib/sparc-sun-solaris2.5/2.7.2/f771 quick.f -quiet -dumpbase quick.f -version -fversion -o /var/tmp/cca003D2.s * GNU F77 version 2.7.2 (sparc) compiled by GNU C version 2.7.2. * GNU Fortran Front End version 0.5.18-960304 compiled: Mar 5 1996 16:12:46 * gcc: Internal compiler error: program f771 got fatal signal 11 * * * ahab% !gdb * gdb /usr/local/lib/gcc-lib/*/*/f771 core * GDB is free software and you are welcome to distribute copies of it * under certain conditions; type "show copying" to see the conditions. * There is absolutely no warranty for GDB; type "show warranty" for details. * GDB 4.15.1 (sparc-sun-solaris2.4), * Copyright 1995 Free Software Foundation, Inc... * Core was generated by * `/usr/local/lib/gcc-lib/sparc-sun-solaris2.5/2.7.2/f771 quick.f -quiet -dumpbase'. * Program terminated with signal 11, Segmentation fault. * Reading symbols from /usr/lib/libc.so.1...done. * Reading symbols from /usr/lib/libdl.so.1...done. * #0 0x43e04 in ffecom_sym_transform_assign_ (s=0x3a22f8) at f/com.c:7963 * Source file is more recent than executable. * 7963 assert (st != NULL); * (gdb) where * #0 0x43e04 in ffecom_sym_transform_assign_ (s=0x3a22f8) at f/com.c:7963 * #1 0x38044 in ffecom_expr_ (expr=0x3a23c0, dest_tree=0x0, dest=0x0, dest_used=0x0, assignp=true) at f/com.c:2100 * #2 0x489c8 in ffecom_expr_assign_w (expr=0x3a23c0) at f/com.c:10238 * #3 0xe9228 in ffeste_R838 (label=0x3a1ba8, target=0x3a23c0) at f/ste.c:2769 * #4 0xdae60 in ffestd_stmt_pass_ () at f/std.c:840 * #5 0xdc090 in ffestd_exec_end () at f/std.c:1405 * #6 0xcb534 in ffestc_shriek_subroutine_ (ok=true) at f/stc.c:4849 * #7 0xd8f00 in ffestc_R1225 (name=0x0) at f/stc.c:12307 * #8 0xcc808 in ffestc_end () at f/stc.c:5572 * #9 0x9fa84 in ffestb_end3_ (t=0x3a19c8) at f/stb.c:3216 * #10 0x9f30c in ffestb_end (t=0x3a19c8) at f/stb.c:2995 * #11 0x98414 in ffesta_save_ (t=0x3a19c8) at f/sta.c:453 * #12 0x997ec in ffesta_second_ (t=0x3a19c8) at f/sta.c:1178 * #13 0x8ed84 in ffelex_send_token_ () at f/lex.c:1614 * #14 0x8cab8 in ffelex_finish_statement_ () at f/lex.c:946 * #15 0x91684 in ffelex_file_fixed (wf=0x397780, f=0x37a560) at f/lex.c:2946 * #16 0x107a94 in ffe_file (wf=0x397780, f=0x37a560) at f/top.c:456 * #17 0x96218 in yyparse () at f/parse.c:77 * #18 0x10beac in compile_file (name=0xdffffaf7 "quick.f") at toplev.c:2239 * #19 0x110dc0 in main (argc=9, argv=0xdffff994, envp=0xdffff9bc) at toplev.c:3927
