(In reply to mike from comment #37)
Try to apply the following debugging patch:
diff --git a/lib/libc/stdio/_flock_stub.c b/lib/libc/stdio/_flock_stub.c
index 069ed64c4e9..64c2d769389 100644
--- a/lib/libc/stdio/_flock_stub.c
+++ b/lib/libc/stdio/_flock_stub.c
@@ -138,4 +138,11 @@ _funlockfile(FILE *fp)
_pthread_mutex_unlock(&fp->_fl_mutex);
}
}
+ else {
+ void *p[3];
+ p[0] = fp;
+ p[1] = curthread;
+ p[2] = fp->_fl_owner;
+ abort2("funlockfile", 3, p);
+ }
}
I wonder if your build dies with a kernel message after it, instead of hanging.
