Created attachment 175620 [details] Poudriere log of failed firefox build Poudriere build of firefox-49.0_8,1 on 10.3-RELEASE-p10 fails during stage I tried a regular build from ports and that one was fine. But options may be different. The build fails with a crash of xpcshell. I attached poudriere log file (with the middle part removed to make it fit in 1MB).

Should be fixed. Re-open if it's not.
Note, I'm gonna re-apply ports r423780 with ports r423781-style fix when landing firefox 50. Recent releases are impossible to build with Clang 3.4 as part of FreeBSD 10.x base system. https://bugzilla.mozilla.org/show_bug.cgi?id=1286204
