Thanks for tracking this down Jan. Should this patch be reverted or
should gcc guality.h be patched to work around the new async default
somehow?

Currently I am using the following patch to guality.h in gcc which seems
to work around it, but I don't really understand why:

diff --git a/gcc/testsuite/gcc.dg/guality/guality.h
b/gcc/testsuite/gcc.dg/guality/guality.h
index 8b657f2..d83e270 100644

Thanks,
