[Bug bootstrap/16986] New: GNAT ICE during make -C gcc gnatlib cross-gnattools ada.all.cross

["fdragon at fdragon dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Trying to build cross compiler for sparc64-unknown-linux-gnu from
i386-unknown-linux-gnu on Slackware 10 using GCC 3.4.1 as host compiler. During
compilation of the gnatlib the following error is thrown. This appears to be
related to PR 11354. The workaround mentioned of using -O instead of the default
-O2 here will allow the compile to finish.

../../xgcc -B../../ -c -g -O2      -W -Wall -gnatpg  a-nscefu.ads -o a-nscefu.o
