Hi Jiangning,

Not sure if you saw it, but Michael Kuperstein committed 25903ef9bc9
which fixed up your test, maybe that's why you're not seeing it now?

I'm using a default cmake command line (i.e., passed no special
options IIRC). Could post the output of cmake -LAH if you think it'd
help :-)

I don't know about the -debug-only flag.

Kind regards,
Charlie.
