I think the (null)'s are odd at least.

2
ltotest.o 15
1068 a2f6b3c8 (null) PREVAILING_DEF
1010 a2f6b3c8 (null) RESOLVED_EXEC
1082 a2f6b3c8 (null) RESOLVED_EXEC
1086 a2f6b3c8 (null) RESOLVED_EXEC
1093 a2f6b3c8 (null) RESOLVED_EXEC
...

First of all, the symbol name should come 4th, not 3rd - the resolution
belongs there.

This means you are very likely using a bogus lto-plugin shared object that
does not match the GCC version you are using.  Though I do not remeber
any version that dumped things in the order I see in your attached file.

So, please check which file is specified as -plugin argument to the linker
(it should be visible in the -v dump) and remove that and/or replace it
with a current version.

Hmm.  We use

      fprintf (f, "%u %llx %s %s\n",
               (unsigned int) slot, symtab->aux[j].id,
               lto_resolution_str[resolution],
               symtab->syms[j].name);

maybe that falls foul of some special Window-ism (aka unportable %llx?).
Kai?
