[sun-sparc-solaris2.6] crash in ObjectPointer_dispatchTo_arity_above_

[nicolas n pelletier]

Hello,

Compiling  the  latest vm.c,  vm.h  with the  lates  cvs  gave me  the
following warning:

vm.c: In function `PSInterpreter_apply_to_arity_withOptionals_':
vm.c:3021: warning: assignment from incompatible pointer type

I  am using  gcc-2.95.2.   Disregarding the  warning  and running  the
generated vm led to a bus error in vm.c:2779.

I recompiled with debug information  to get more information about the
crash, and include it here in the hope it will help.
