--- Comment #4 from Gary Mills <gary_mills at fastmail dot fm> ---
sparcv7 is a file path component.  It implies that this is a 32-bit executable
running on a 64-bit kernel.  That's normal behavior on OI and Solaris builds.
Generally there are both 32 and 64-bit builds.  The 64-bit executables reside
in
a sparcv9 directory.

I don't see anything in the various FLAGS that might cause this ICE.

I still need full instructions on how to use gdb to determine if the ICE is
caused by an alignment error.
