libpthread lock assertion failed

[Rene Ladan]

Hi,

when trying to build gtksourceview-sharp-0.5 by hand (it isn't in the
ports yet), I got the following lock assertion failure:

Assertion failed: (lu->lu_myreq->lr_owner == lu), function _lock_acquire, file 
/usr/src/lib/libpthread/sys/lock.c, line 171.

void
_lock_acquire(struct lock *lck, struct lockuser *lu, int prio)
{
        int i;
        int lval;

        /**
         * XXX - We probably want to remove these checks to optimize
         *       performance.  It is also a bug if any one of the

#if 0
        if (lck == NULL || lu == NULL || lck->l_head == NULL)
                return;
#endif
        if ((lck->l_type & LCK_PRIORITY) != 0) {
                LCK_ASSERT(lu->lu_myreq->lr_locked == 1);
                LCK_ASSERT(lu->lu_myreq->lr_watcher == NULL);
                LCK_ASSERT(lu->lu_myreq->lr_owner == lu); <-- this one
                LCK_ASSERT(lu->lu_watchreq == NULL);

                lu->lu_priority = prio;
        }

This was after

[configure/gmake blah]
/usr/local/bin/mcs --unsafe --target library /pkg:gtk-sharp /pkg:gnome-sharp \
generated/*.cs ./GtkSourceView.cs ./AssemblyInfo.cs -o gtksourceview-sharp.dll

Apart from the failed compilation, there seems to be no further harm.
