Bug#245584: gcc-3.3: [m68k] internal compiler error: in verify_local_live_at_start, at flow.c:601
Package: gcc-3.3
Version: 1:3.3.3ds6-6
Severity: important
gcc-3.3 segfaults on m68k when trying to build certain kernel drivers in
linux-2.4.26 (and below). For this reason 2.4 kernels on m68k currently have
to be built with gcc-2.95.
gcc-3.3 -v -save-temps -D__KERNEL__ -I/home/cts/build/2.4.26/kernel-headers-2.4.26-m68k-2.4.26/kernel-source-2.4.26/include -Wall -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -O2 -fomit-frame-pointer -pipe -fno-strength-reduce -ffixed-a2 -nostdinc -iwithprefix include -DKBUILD_BASENAME=ide_cd -c ide-cd.c

I've built an i386 -> m68k crosscompiler with gcc-3.3 (toolchain-source 3.3-2)
which gives the same ICE with the same source file.
