I'd guess that's Windows polite version of Seg Fault ot Bus Error :)
I know ~0 about windows but I seem to recall that there _might_ be
something useful in the system event logs.

When you get a moment could you try this change:
--- DBI.xs (revision 15137)
+++ DBI.xs (working copy)
@@ -3536,7 +3536,7 @@
}
}
- if (is_orig_method_name)
+ if (0 && is_orig_method_name)
imp_msv = (SV*)inner_method_lookup(aTHX_ DBIc_IMP_STASH(imp_xxh),
cv, meth_name);
else
which will, I think, effectively disable the runtime side of the method
cache changes.
