Gallium pipe-loader patch
Hello. I've tried OpenCL using lang/clover provider and encountered some problems in mesa ports (can be fixed patching graphics/mesa-dri). I use FreeBSD 11.1 and have the port tree updated with portsnap and packages updated with portupgrade
1) OpenCL applications do not work in X11 environment. I have exactly the same problem as described here: bug #214204 (*) The fix is still the same, maybe this is a regression. I attach patch which is combined from an old patch in graphics/mesa-dri/files and the fix. I still do not know how to link -lxcb to opencl targets. Autoconf is very complicated for me, so I do not know what to do.
2) When I call clReleaseContext() from my program, it finishes OK, but program crashes with segmantation fault when calls atexit handlers, having very strange backtrace:
#0 0x0000000808534500 in ?? ()
#1 0x0000000800b754d5 in __cxa_finalize (dso=0x0) at /usr/src/lib/libc/stdlib/atexit.c:237
#2 0x0000000800b063d1 in exit (status=0) at /usr/src/lib/libc/stdlib/exit.c:72

#4 0x0000000800625000 in ?? ()
#5 0x0000000000000000 in ?? ()
clinfo has the same behaviour. I do not know the solution. Any suggestions?
