Hi,
I downloaded, compiled and installed insight successfully
from insight+dejagnu20001115 but I have problems starting
gdb. It starts okay with the -nw option, but otherwise
creates a segfault after a second of thinking.
I dumped the core and had a look, it discovers some error,
tries to print the error with vprintf and stuffs up the
argument list and crashes WITHOUT printing the error.
Attached is the text of the stack. If anybody could give me
a hand figuring out what my problem is it would be much
appreciated.
Thanks a lot in advance,
Best Regards,
Jochen

I didn't see any other responses on the list, so here's my offering:
I had the same problem with insight+dejagnu20001118 compiled with
gcc version 2.96 20000731 (Red Hat Linux 7.0). My quick and dirty fix
was to change gdb/symtab.c:120 from
char no_symtab_msg[] = "No symbol table is loaded. Use the \"file\" command.";
to
const char *no_symtab_msg = "No symbol table is loaded. Use the \"file\" command.";
For reasons that escape me, the pointer to no_symtab_msg was being
mangled in the call to error(const char *string,...) with the first
declaration. An issue with the compiler, I expect. What worries me
about the quick fix above is that there are many other message
declarations in the source with a similar declaration that may or may
not cause the same fault. Unfortunately I don't have the time to look
at the problem any deeper, but so far the debugger has been working OK.
Regards,
Jon
