What does "using" mean here?  Do you mean defining GC_MARK_STACK to
GC_USE_GCPROS_AS_BEFORE rather than to GC_MAKE_GCPROS_NOOPS?

(And Sven's probably right -- using -O1 may also avoid this failure.  I
 had removed the special-casing we had in 23 (to set -O1 rather than -O2
 on ia64), in order to see if 24 still needed it, and then forgot about
 the change.)

Thanks
