>Description:
[ Reported to the Debian BTS as report #168086.
Please CC 168086@bugs.debian.org on replies.
Log of report can be found at http://bugs.debian.org/168086 ]
The attached testcase ICEs on arm-linux with 3.2 branch 20021212 (-O2
only, not -O). As the 3.3 branch doesn't bootstrap, I cannot check with 3.3.
g++-2.95 did work ok, so this is a regression.
