Internal compiler error in `store_bit_field', at expmed.c:277.

It seems that I've come across a case where compiling with gcc 2.95.4 (from the
Debian package 2.95.4-22) using -O3 crashes, while compiling with no
optimization does not crash.

I will attach the .i file produced with -save-temps. I'm experiencing:

$ gcc -O3 -c bm_kiss_double.cil.i
...
./bm_kiss_double.cil.c: In function `hcu_restore_frame_of___sgnl_v1':
./bm_kiss_double.cil.c:4273: Internal compiler error:
./bm_kiss_double.cil.c:4273: Internal compiler error in `store_bit_field', at
expmed.c:277
Please submit a full bug report.
See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.


I'm using the gcc 2.95.x series in a performance evaluation of various
compilers.

I did not try to reproduce with gcc 2.96 or gcc 2.97 (I don't see them being
available for Debian).

I confirmed that gcc 3.3.5 does not have this problem.

Well 2.95.4 is almost 6 years old and is no longer being maintained and has not
for at least 5 years.  Since you already mention this is fixed 3.3.5 I am going
to close as being fixed there.  Also note any release before 4.1 is no being
maintained any more either so you should update to a newer release or have
someone else support it for you.
