Undefined line in gdb

RogerVI — Wed, 16 May 2007 17:02:16 GMT

The operating system is Hp-UX 11i

I'd compiled a program with -g option
I run this program (called genfhist.exe) and resulted in core dumped:

Bus error (core dumped)

Then, I want to know what is the line in the program that caused the error, but I can't
I used the gdb debugger but not show me the line number or function name

#gdb -c core
Detected 64-bit corefile.
Invoking /opt/langtools/bin/gdb64.

Can somebody help me, please ?
Thanks in advance

Imho the gdb you are using is built for HP-UX 11.0 not 11i. You most likely need the 11i version of gdb.

First of all, gdb 2.1 is obsolete. This may prevent it from doing a stack trace. The latest is 5.6. You can download this from:
http://www.hp.com/go/wdb

Your signal 10 is occurring in some shared lib.
Have you tried running it in the debugger?
