Subject [users@httpd] SIGSEGV in apr_proc_mutex_trylock on FreeBSD 4.7
Date Mon, 04 Nov 2002 19:28:02 GMT
I've tried using both FCNTL and SYSVSEM locks, but either way I get a 
segfault when trying "apr_proc_mutex_trylock" on the mutex.

Both lock and unlock work, and I'm passing the same arguement in the same context
. Here is the stack trace I get:

Program received signal SIGSEGV, Segmentation fault.
0x0 in ?? ()

where ... is my handler code.

Any thoughts on this?
