RE: gdb is coring on me, "bus error"

["Grant Schoep" <gschoep at digitalglobe dot com>]

update, well I figured out what is causing the problem. It is a specific
.so file I am linking in to the app.

If I remove the code that needs that library, and remove the " -Bdynamic
-lbadlib " from my link line... all works good.

Any ideas as to why this may be? ... is there a way I can tell the
debugger to ignore this library? The calls in this library I don't want
to debug anyways. Just my app.

Subject: gdb is coring on me, "bus error"


My Setup...

-Solaris 9
-gdb version 6.0(was prebuilt version from http://www.sunfreeware.com/)

The "gdb -v" output.
GNU gdb 6.0
...snip...
This GDB was configured as "sparc-sun-solaris2.9".


Ok, gdb seems to debug a number of apps fine. I have one app that I am
just starting to develop and whenever I run the apps under gdb, gdb
itself core dumps with a bus error...

This particular app is rather funky with threads and socket use. Is
there any known issues? 

Oh... I also believe that some of the libaries that I need to link to
were built by the Sun Pro compier. Are these "known problems?"

I've built my own version of gdb, so I could debug it a bit more(still
cores in same way). Stack trace from it is as follows.

(gdb) where
#0  0xff0428e4 in t_splay () from /usr/lib/libc.so.1
#1  0xff042750 in t_delete () from /usr/lib/libc.so.1
#2  0xff0423a0 in realfree () from /usr/lib/libc.so.1
#3  0xff042b8c in _free_unlocked () from /usr/lib/libc.so.1

Any ideas on what I could look into or what I am doing wrong?
