Hi,

FWIW, while running Mozilla 1.6 (from pkgsrc) on NetBSD 1.6ZH today, the
program died twice:

rainforest:bstark$ mozilla
mozilla-bin: Error detected by libpthread: Invalid mutex.
Detected by file "/usr/src/lib/libpthread/pthread_mutex.c", line 312,
function "pthread_mutex_unlock".
See pthread(3) for information.
rainforest:bstark$ mozilla
mozilla-bin: Error detected by libpthread: Invalid mutex.
Detected by file "/usr/src/lib/libpthread/pthread_mutex.c", line 312,
function "pthread_mutex_unlock".
See pthread(3) for information.
rainforest:bstark$


My system was built January 16th, 2004 and my version of pthread_mutex.c
is:

  $NetBSD: pthread_mutex.c,v 1.17 2003/11/24 23:54:13 cl Exp $

The place in the file where the program died looks like this:

int
pthread_mutex_unlock(pthread_mutex_t *mutex)
{
        struct mutex_private *mp;
        pthread_t self, blocked;
        int weown;

        pthread__error(EINVAL, "Invalid mutex",
            mutex->ptm_magic == _PT_MUTEX_MAGIC);     <-- this is line 312

[.. remainder of function deleted for space ...]


I wasn't doing too much with Mozilla -- just browsing the Dell.com web
site looking for a new laptop.

I don't see any core files, so there isn't much else to report. Anyone
else seen this?
