You hit an optimizer compiler bug on Solaris.
The best thing to do, is to comment out these lines in
mx/DateTime/mxDateTime/mxDateTime.c (near the top):
/* Define these to have the module use free lists (saves malloc calls) */
#define MXDATETIME_FREELIST
#define MXDATETIMEDELTA_FREELIST
and then recompile the egenix-mx-base package.
