 From Pierre Bechetoille on blfs-dev:
 I encountered a new issue with latest firefox compiled with gcc-6.

 I had very frequent random crashes. But never in safe mode. I finally
 found that setting "javascript.options.baselinejit" to false in
 about:config fixes the crashes.

 Googling on Firefox JIT compiler problems, I found that:
 https://bugzilla.mozilla.org/show_bug.cgi?id=1218925 (crash in
 js::jit::CodeGenerator::generateBody) and
 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70526#c14 (GCC 6 miscompiles
 Firefox JIT compiler)

 I don't know if it is a firefox or a gcc bug, nevertheless I recompiled
 firefox with the patch given in the first link (addition of -fno-schedule-
 insns2 to CFLAGS and CXXFLAGS in js/src/Makefile.in) and since I have no
 more crash !
