Bug 592840 – www-client/firefox-48.0.1 with gcc-6 needs -flifetime-dse=1 or it segfaults

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Martin Väth 2016-09-04 06:40:12 UTC]

If firefox-48.0.1 is compiled with gcc-6.2.0, it segfaults at startup even with an empty profile. Adding -flifetime-dsa=1 fixes the problem.

emerge info and a backtrace is required before mozilla team will be able to do anything please.

gdb bt

The backtrace corresponds to emerge --info (USE=-gtk2),
but the segfault occurs also with USE=gtk2

append proper support flags for gcc6

Feel free to test this, you should exclude the included gcc-6 support patch from the build

>=Firefox-49 is now supported via tree with gcc-6 thanks for reporting.
