I suppose you can provide at least a backtrace and some debug_rtx output?

C testcase (-m64 -O2):
struct S { const char *d, *e; } __attribute__((packed));
void
foo (const char **p, struct S *q)
{
*p = "abcdef";
q->d = "ghijk";
}
I'd say the bug is in the section anchor support (and the bug goes away with
-O2 -fno-section-anchors; so I'd expect this is a regression since
-fsection-anchors has been introduced and made default on ppc64), because
expand_normal on ADDR_EXPR of the STRING_CST returns a PLUS (which IMHO should
be ok only for EXPAND_SUM etc. but not EXPAND_NORMAL).

libgo builds with this fix.
libgo now fails to run every test (see PR52084).
