Subject: [Bug target/42536] New: [4.4/4.5 regression] ICE in spill_failure, at reload1.c:2141
Date: Tue, 29 Dec 2009 12:41:00 -0000 [thread overview]
Message-ID: <bug-42536-5724@http.gcc.gnu.org/bugzilla/> (raw)
seen with 20091228 trunk and 4.4 branch on i486-linux-gnu, not seen with 4.3
branch (opening new report, because PR39431 is fixed for 4.4 and 4.5). Adding
-fomit-frame-pointer avoids the ice.
