Bug 594010 – dev-scheme/guile-2.0.12-r1 Fails to compile with internal compiler error: SSA corruption

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Gary Stein 2016-09-16 20:12:18 UTC]

Recent upgrade of guile from 1.8.8-r2 to guile-2.0.12-r1 fails to compile, with an odd compiler error.  In the grand scheme of things running older gcc version 4.9.3.

the actual error:
make[3]: Entering directory '/var/tmp/portage/dev-scheme/guile-2.0.12-r1/work/guile-2.0.12/libguile'

Was able to fix with a patch I found online:
https://github.com/maximeh/buildroot/blob/master/package/guile/0004-workaround-ice-ssa-corruption.patch

Which looks fairly old, and is for ARM even though I'm on amd64, but the same error.  Hate to say it works for me, but hopefully it helps anyone else that has had this bug.


Reproducible: Always
