Bug#457104: gcc-4.2: [hppa] ICE when building cfitsio3

[Aurelien Jarno <aurel32@debian.org>]

Package: gcc-4.2
Version: 4.2.2-4
Severity: important

Hi,

cfisio3 FTBFS on hppa with a gcc ICE:

cc -c -g -O2 -D_REENTRANT -DgFortran -DPACKAGE_NAME=\"\" -DPACKAGE_TARNAME=\"\" -DPACKAGE_VERSION=\"\" -DPACKAGE_STRING=\"\" -DPACKAGE_BUGREPORT=\"\" -DSTDC_HEADERS=1 -DHAVE_SYS_TYPES_H=1 -DHAVE_SYS_STAT_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MEMORY_H=1 -DHAVE_STRINGS_H=1 -DHAVE_INTTYPES_H=1 -DHAVE_STDINT_H=1 -DHAVE_UNISTD_H=1 -DHAVE_STDLIB_H=1 -DHAVE_STRING_H=1 -DHAVE_MATH_H=1 -DHAVE_LIMITS_H=1 -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64 -DHAVE_FTRUNCATE=1 -DHAVE_LONGLONG=1 -DHAVE_SHMEM_SERVICES=1 -DHAVE_NET_SERVICES=1  eval_y.c

make: *** [build-stamp] Error 2

It happens with -O2 or -O3, but not with -O1. gcc-4.1 is not affected.
Reduced testcase attached.

Cheers,
