So bind9 itself doesn't find its own symbols.  I'm then not surprised
that gdb can't either. Trying a trivial example:

int main(void) {  *(int*) 0 = 0; }

gives

€ gdb ./test core
[...]
Program terminated with signal SIGSEGV, Segmentation fault.

warning: Unexpected size of section `.reg2/903' in core file.
#0  main () at test.c:5
5               *(int*) 0 = 0;

So it seems to work at least basically.
