Huh, there isn't even such a union in the testcase ;)

On x86_64-linux for this testcase I get

FAIL: gcc.dg/guality/pr43077-1.c  -O2 -flto -flto-partition=none  line 42 varb
== 2
FAIL: gcc.dg/guality/pr43077-1.c  -O2 -flto  line 11 varb == 2
FAIL: gcc.dg/guality/pr43077-1.c  -O2 -flto  line 19 varb == 3
FAIL: gcc.dg/guality/pr43077-1.c  -O2 -flto  line 42 varb == 2

instead.

That said, there are numerous known issues with debug support and LTO, but
most of the guality fails would be nice to have analyzed as C debug support
should be basically "complete".

The type is coming from libc debuginfo.

Seems to be fixed with recent enough gdb(?)
