Reduced testcase:
extern void abort (void);
struct A
{
struct A *a;
};
struct B
{
struct A *b;
};
__attribute__((noinline))
struct A *
foo (struct A *x)
{
asm volatile ("" : : "g" (x) : "memory");
return x;

Sorry. Does this one look right? It's actually .c I typo'd the .cc.

That is the assembler that is produced not the preprocessed source, use
-save-temps and attach the .ii file.
Thanks,

Hmm, so -fwrapv and -fno-strict-aliasing fixes the problem which case it might
be a bug in the source.
Can you provide the preprocessed source of pith/reply.cc?
