--- Comment #37 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> ---
Here on NIST I do not get any failures.  FM908 passes FM905 and FM907 require
inspection to confirm and they look good.  I only need to adjust the reference
output file that is used by the script to do the inspection for me.

Dominiq, can you try FM908 with something like Valgrind and also try different
optimization levels and see if anything odd pops up.

--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
The code compiles with r200946 (2013-07-14), but gives the ICE with r201631
(2013-08-09). It could be r200954. The backtrace is similar to the one for
pr58880 (duplicate?).

Very likely.

Indeed, it started with r200954.

Looks similar to PR60495; the patch there (committed) solved the ICE problem
but the following issue remains (with both PRs): undefined reference to
`__final_a_T2.2437'
