I said Fsignal, but posted a patching breaking in signal_or_quit. The
latter only exists in emacs-26. Are you running that or 25.2 as in your
original report?
Actually I think it might work better to break in longjmp instead.

I believe this means that the problem is indeed a non-local exit
happening somewhere in there, but we failed to catch it. Either because
I posted the Emacs 26 version while you are on Emacs 25, or it doesn't
go through the signal machinery at all.
