Known problems in GDB 5.3 See also: http://www.gnu.org/software/gdb/bugs/ *-*-freebsd* --------------- Due to a kernel bug (kern/35175), detaching from an attached process will very likely cause the process to be stop or die with a Trace/BPT trap. i386-*-freebsd[34]* ------------------- There is a bug (bin/41671) in FreeBSD's gcc that causes it to emit bad debug information when using the stabs format (which is the default). As a result GDB tends to place breakpoints on functions before the function prologue, and information about function parameters and local variables is lost. In earlier versions of GDB the effects were rather limited, but starting with GDB 5.3 the influence is much more prominent. As a workaround, compile your code with -gdwarf-2. hppa2.0-hp-hpux10.20 -------------------- gdb/487: The top level make files used to build GDB are not compatible with HP/UX make. As a workaround, use GNU make. gdb/486: The HP/UX C compiler defaults to K&R mode but GDB only builds with an ISO C compiler. The top level configuration incorrectly sets CC to `cc' instead of `cc -Ae'. As a workaround, the correct compiler can be specified as part of the configuration vis: $ 'CC=cc -Ae' ./configure s390*-*-* --------- gdb/513: GDB does not build on s390 GNU/Linux. The problem should be fixed in more recent sources. i386-*-freebsd4.4* ------------------ gdb/455: GDB doesn't build on a FreeBSD 4.4-STABLE system. The problem is still being investigated. alpha*-*-osf* ------------- gdb/816: When building GDB with GCC 3.0.1, GDB is unable to load a core file properly. It generates several errors and warnings regarding unhandled core file section types, incorrect endianness, the failure to load the registers. Are also incorrectly reported: The program name, the cause of the program death, and the call stack at the moment of the death. This problem has been reported on alpha-osf4.0f and alpha-osf5.1a. To work-around the problem, add -D__digital__ to the CFLAGS when building GDB vis: $ make CFLAGS='-O2 -D__digital__' i[3456]86-*-linux* ------------------ gdb/1030: GNU binutils 2.12.1 and earlier versions do not work properly with gdb. If you use GNU binutils, upgrade to version 2.13 or later. You can check the version of binutils with the command: $ ld --version
