I can confirm it is graphite failing. It emerges fine with -floop-interchange -floop-strip-mine -floop-block -fgraphite-identity removed from CFLAGS.
Can you pinpoint which flag of those 4 triggers the ICE?
Created attachment 404360 [details] build log with -fraphite-identity The same error is triggered by -fgraphite-identity alone. Here is an xz-compressed build log. The same ICE is also triggered with -floop-strip-mine alone but in another source file. I will post the log shortly.
Created attachment 404362 [details] build log with -floop-strip-mine Build log with -floop-strip-mine. The ICE occurs at another source file than with -fgraphite-identity.
Thanks. The problematic flags are now filtered for qtwebkit. 31 May 2015; Davide Pesavento <pesa@gentoo.org> qt4-build-multilib.eclass: Blacklist graphite-related flags that cause ICEs on qtwebkit (bug 550780). I'm reassigning this bug to toolchain to see if they're interested in fixing it.
considering how much rewrites lto/graphite have gone through in each gcc release so far, if it works with the latest (5.1.0), i think that's all we plan on doing.
The bug is not reproducible with GCC 5.1.0.
if it was backported, or the fix that went into trunk identified, we can add it to 4.9, but lto/graphite aren't a priority for us currently
(In reply to SpanKY from comment #10) > if it was backported, or the fix that went into trunk identified, we can add > it to 4.9, but lto/graphite aren't a priority for us currently Closing since noone has yet identified the commit / bug, and 5.4 is stable now.
