My ODroid U3 has become my defacto build server: made a separate “debug” makepkg.conf for OpenJDK8. Easy enough to use for Firefox to figure out what’s segfaulting
I can’t pinpoint exactly what is wrong with OpenJDK8, but it seems to be pthread and/or ld related. My previous lazy debugging attempt on Firefox/Thunderbird seemed to be a pthread problem as well. My suspicion is there’s an annoying bug in the newest glibc for ARM.
And right after that: an update pushed that fixed Firefox!
