Known problems in GDB 5.1.1 See also the bug database http://www.gnu.org/software/gdb/bugs/ Contrary to the GDB 5.1.1 announcement, the update did not contain fixes to a i386 floating point problem. The latest sources do contain the fix and it will be included in GDB 5.2. Known problems in GDB 5.1 hppa2.0-hp-hpux10.20 Due to a problem (conflicting types) with libiberty/regex.c, GDB 5.1 does not build on HP/UX 10.20 when using the HP supplied compiler. Due to bit rot, GDB 5.1 does not work on HP/UX 10.20 when built with GCC. hppa2.0w-hp-hpux11.00 Due to a problem with ltconfig and long argument lines, GDB 5.1 does not configure on HP/UX 11.00. alpha-dec-osf5.1 GDB 5.1 has a number of problems on this platform (Ref PR gdb/237). A GDB 5.1 built with ``CC="cc -DUSE_LDR_ROUTINES"'' is reported to work much better. alpha-dec-osf4.0e GDB 5.1 is known to have problems on this platform (encounters an internal error in the symbol table reader). sparcv9-sun-solaris2.8 There are known problems with building GDB 5.1 using GCC 3.0.x for the 64 bit SPARC target (bad code gen). You could try a development version of GCC. i586-sco-sysv5uw7.1.1 There are known problems with GDB 5.1's thread support on this platform. Non-threaded programs should work. *-*-* GDB 5.1 assumes that the host C compiler implemends alloca(). GCC is one such compiler. This problem should be fixed on the trunk.
