Bugs section of the GDB manual (gdb/doc/gdb.texinfo) or the gdb/CONTRIBUTE file. -Known bugs: - - * Under Ultrix 4.2 (DECstation-3100) or Alphas under OSF/1, we have - seen problems with backtraces after interrupting the inferior out - of a read(). The problem is caused by ptrace() returning an - incorrect value for the frame pointer register (register 15 or - 30). As far as we can tell, this is a kernel problem. Any help - with this would be greatly appreciated. - - * Under Ultrix 4.4 (DECstation-3100), setting the TERMCAP environment - variable to a string without a trailing ':' can cause GDB to dump - core upon startup. Although the core file makes it look as though - GDB code failed, the crash actually occurs within a call to the - termcap library function tgetent(). The problem can be solved by - using the GNU Termcap library. - - Alphas running OSF/1 (versions 1.0 through 2.1) have the same buggy - termcap code, but GDB behaves strangely rather than crashing. - - * On DECstations there are warnings about shift counts out of range in - various BFD modules. None of them is a cause for alarm, they are actually - a result of bugs in the DECstation compiler. - - * Notes for the DEC Alpha using OSF/1: - The debugging output of native cc has two known problems; we view these - as compiler bugs. - The linker miscompacts symbol tables, which causes gdb to confuse the - type of variables or results in `struct ' type outputs. - dbx has the same problems with those executables. A workaround is to - specify -Wl,-b when linking, but that will increase the executable size - considerably. - If a structure has incomplete type in one file (e.g., "struct foo *" - without a definition for "struct foo"), gdb will be unable to find the - structure definition from another file. - It has been reported that the Ultrix 4.3A compiler on decstations has the - same problems. - - * Notes for Solaris 2.x, using the SPARCworks cc compiler: - You have to compile your program with the -xs option of the SPARCworks - compiler to be able to debug your program with gdb. - Under Solaris 2.3 you also need patch 101409-03 (Jumbo linker patch). - Under Solaris 2.2, if you have patch 101052 installed, make sure - that it is at least at revision 101052-06. - - * Under Irix 5 for SGIs, you must have installed the `compiler_dev.hdr' - subsystem that is on the IDO CD, otherwise you will get complaints - that certain files such as `/usr/include/syms.h' cannot be found. - - * Under Irix 6 you must build with GCC. The vendor compiler reports - as errors certain assignments that GCC considers to be warnings. - - GDB can produce warnings about symbols that it does not understand. -By default, these warnings are disabled. You can enable them by -executing `set complaint 10' (which you can put in your ~/.gdbinit if -you like). I recommend doing this if you are working on a compiler, -assembler, linker, or GDB, since it will point out problems that you -may be able to fix. Warnings produced during symbol reading indicate -some mismatch between the object file and GDB's symbol reading code. -In many cases, it's a mismatch between the specs for the object file -format, and what the compiler actually outputs or the debugger -actually understands. - Graphical interface to GDB -- X Windows, MS Windows ========================== -- cgit v1.2.3
