[Bug middle-end/19084] New: ICE: internal consistency failure

[aj at gcc dot gnu dot org]

Compiling glibc with "gcc -m32" on Linux/AMD64 gives me the following
ICE with current GCC CVS:

 /opt/gcc/4.0-devel/libexec/gcc/x86_64-suse-linux-gnu/4.0.0/cc1 -fpreprocessed
lcong48_r.i -quiet -dumpbase lcong48_r.c -m32 -march=i686
-mpreferred-stack-boundary=2 -auxbase-strip
/builds/glibc/4.0-linuxthreads-32bit/stdlib/lcong48_r.o-g -O2 -Wall -Winline
-Wstrict-prototypes -Wwrite-strings -std=gnu99 -version -o lcong48_r.s
GNU C version 4.0.0 20041219 (experimental) (x86_64-suse-linux-gnu)
        compiled by GNU C version 4.0.0 20041219 (experimental).
GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096
lcong48_r.i: In function '__lcong48_r':
lcong48_r.i:37: fatal error: internal consistency failure
compilation terminated.
