Thank you for quick fix. I tested that patch on top of r169501 (I tested it
before with r169450, but deleted the results...) - bootstrap with yes,rtl,df
checking went fine, check with
RUNTESTFLAGS="--target_board=unix/-fschedule-insns2/-fsched2-use-superblocks/-fmodulo-sched/-fcompare-debug"
showed no ICEs, -fcompare-debug failures or exec failures caused by that patch.
(languages=c,c++,lto,fortran)
