Description Rainer Orth 2014-08-05 12:21:25 UTC 
Between 20140725 (r213049) and 20140801 (r213453) occured a testsuite regression
on Solaris (both sparc and x86, 32 and 64-bit):

FAIL: g++.dg/lto/20100302 cp_lto_20100302_0.o-cp_lto_20100302_1.o link, -flto -fabi-version=2 (internal compiler error)
UNRESOLVED: g++.dg/lto/20100302 cp_lto_20100302_0.o-cp_lto_20100302_1.o execute -flto -fabi-version=2

The failure boils down to

./lto1 -quiet -fwpa cp_lto_20100302_0.o cp_lto_20100302_1.o

I can attach the .o files if this helps.

I'm quite sure it's Honzas fault.
Comment 2 Richard Biener 2014-11-19 14:01:18 UTC 
Still failing?

> Still failing?

Gone again since 20140822.
