Call to set_com_err_hook() triggers abort

[Isaac Boukris]

Hello,

We are getting random core dumps of httpd on our QA machines and I'm
trying to understand what could cause it.
We have some initialization code which calls set_com_err_hook() with a
static C++ class method, and the crash occurs right afterwards (looks
like com_err_initialize return error, but I have no further info for
now as it happens randomly).

The top of the stack looks like this:
Program terminated with signal 6, Aborted.
#0  0xffffe410 in __kernel_vsyscall ()
(gdb) bt
#0  0xffffe410 in __kernel_vsyscall ()
#1  0xf7d94ba0 in raise () from /lib/libc.so.6
#2  0xf7d964b1 in abort () from /lib/libc.so.6
#3  0xf7251acf in set_com_err_hook (
    new_proc=0xf6565180 <CPP_NS::CPP_CLASS::CPP_STATIC_METHOD(char
const*, long, char const*, char*)>) at com_err.c:156

Anyone seen this before? Any idea what may be the cause of it?

Thank you!
