I am using a slightly different command line, "perl -MO=Xref -MWin32::API
-E"0"". Its generating a segv as you have.
I get
First-chance exception at 0x100018e2 (B.dll) in : 0xC0000005: Access violation
reading location 0x0000000a.

the gv in XSUB XS_B__GV_STASH, is type 9, which means GV, yet sv_u, is a string
pointer to the string/PV "num". Also in the SV body, it has magic of type "B"
(#define PERL_MAGIC_bm 'B' /* Boyer-Moore (fast string search) */)
and vtable of PL_vtbl_bm. Which is very wrong for a GV. I have to figure out
where I am in PP and where it got this broken GV from.
