Can you look at gdb/config.in in the build directory, and tell
me if the following macro is defined?
HAVE_PT_GETDBREGS
I have #undef HAVE_PT_GETDBREGS
That explains it why you get the SEGV...
I don't have FreeBSD 8.2 lying around, can you see if
PT_GETDBREGS is defined in /usr/include/sys/ptrace.h?
#define PT_GETDBREGS 37 /* get debugging registers */
But that doesn't explain why it's undef'ed in your case. For that,
you're going to have to look inside the gdb/config.log file,
and search for PT_GETDBREGS. It should tell you that the compilation
failed, what source file was used, and why it failed.
