Bug#633469: ICE: gcc-4.6: ICE on armhf with traverso-0.49.2-3

[Konstantinos Margaritis]

Package: g++-4.6
Version: 4.6.1-2
Severity: important

Hi,

g++ fails with an ICE on package traverso on armhf:

http://buildd.debian-ports.org/status/fetch.php?pkg=traverso&arch=armhf&ver=0.49.2-3&stamp=1307331580

Attached is the smallest trimmed down file that is able to reproduce the ICE:

$ g++-4.6 -O2 -c memops_testcase.cpp -o memops_testcase.o
memops_testcase.cpp: In function ‘void sample_move_d32u24_sS(char*,
audio_sample_t*, long unsigned int, long unsigned int,
dither_state_t*)’:
memops_testcase.cpp:28:1: internal compiler error: in
get_arm_condition_code, at config/arm/arm.c:17152
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.6/README.Bugs> for instructions.

Regards
