It segfaults in:
0xb7ff4a10 in XS_Devel__FindRef_find_ (my_perl=0x804b008, cv=0x819faa0)
at FindRef.xs:217
217 if (GvCV (sv) == (CV *)targ)
res_gv ('&');
It dereferences invalid pointer sv (= 0xb).
I tried to minimize the test case, but without a luck. Calling
Devel::FindRef only is fine. Minimal crashing script is attached. There
is something bad. E.g. removing last letter `n' from `...actually prin'
comment disappears the segfault.
