Bug 240761: Segmentation fault in OpenCL programs using clover
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=240761



--- Description ---
Hello. This is a long standing bug (at least for me), but I've decided to
report only now. When you use an OpenCL program using lang/clover, the programm
will crash at exit.

I've tracked the problem to a file src/util/u_queue.c in mesa sources. The
segmentation fault occurs while executing atexit handlers (one such hander is
added in global_init() ). BTW, there is nothing wrong with atexit_handler()
function itself: it can be empty and the result will be the same (segmentation
fault).

I tried to reproduce this behavior in a test program without success, so I have
no idea what is causing the bug.

Meanwhile, I wrote a little workarond using constructor and destructor
functions (supported by both clang and gcc). This works just fine without any
errors.
