SIGBUS On Solaris 8

I've compiled XEphem 3.4 on Solaris 8 x86, and it seems to work just fine. On Solaris 8 SPARC, I'm getting a SIGBUS in ta_par().

Like this:

breccia-180% ./xephem
Bus Error (core dumped)

breccia-181% gdb xephem

I've checked for optimizer bugs, and have double checked to make sure the various compiler flags are identical. The x86 build sets "-Dasm=__asm", and the SPARC build doesn't. Otherwise, both should be identical. Compiler is gcc 2.95.2.

Anyone have any ideas?
