Description cbl 2015-09-16 16:27:38 UTC 
Running FreeBSD 10.2-p2 on amd64.  Installing ImageMagick-nox11 from source specifically with OpenMP and Threads options selected.  Installs correctly, but when I try to run "convert -version", the process hangs.  Recompiling withOUT OpenMP and binaries as expected.  I've tried linking against GCC 4.8, 4.9 and 5.2 libraries and all give me the same result when OpenMP is compiled in.   I am able to reproduce on another 10.2/amd64 box.

Backtrace output:

Also just tried recompiling ImageMagick fresh after updating to 10.2-RELEASE-p3. Same result.
Comment 2 Koop Mast freebsd_committer freebsd_triage 2015-09-17 10:13:05 UTC 
I can't reproduce this and it annoys me greatly. I have done the same, install everything IM needs from packages and build a custom IM with OpenMP support enabled. Do you have any other non-default options apart from OpenMP enabled?

OpenMP will always use lang/gcc, which is gcc 4.8.

Comment 3 cbl 2015-09-17 19:58:17 UTC 
I figured it out.  

The ones I have been experiencing the issues on are running some large ZFS pools. Both had some boot/loader.conf settings set:
kern.maxdsiz="2147483648" # 2GB
kern.dfldsiz="2147483648" # 2GB

Those settings worked fine on <10.2 with IM+OpenMP, but not on 10.2+.   After commenting those /boot/loader.conf settings out, rebooting, the exact same IM+OpenMP works as expected.   Sorry for the noise.
