There are the following issues:

 a) with -DFILL_DEAD_DEFAULT=0 -DFILL_ALIVE_DEFAULT=0 -DFILL_CHECK_DEFAULT=0
    (added through Configure on Tru64) it should run OK;

 b) with

	env PERL_MALLOC_OPT="d=1;a=1;c=1" perl ...

    the failure should reappear; my conjecture would be that just
    d=1;a=1 would not trigger the failure.

 c) a dump of 32 bytes after (and before) ovp might clear things a tiny bit.

[I do not think that I have time to muck with True64 account; so if
'a' works, maybe it is better to lieve the sleeping dog lie...]

Thanks,
Ilya
