[PATCH 0/1] MR2126: ntdll: Print an error if we receive a signal not on the signal stack.

[Zebediah Figura (＠zfigura)]

Without this patch the process will silently die.

I managed to trigger this while trying to trace Child of Light with Renderdoc,
the latter of which crashed in its own "TargetControlServerThread".

This, confusingly, manifested in the game restarting itself without the Ubisoft
overlay; apparently the game or one of its launchers was capable of recognizing
when the process had died and restarting it, but would not try to inject the
overlay a second time. I have not investigated the cause of the crash; it is not
unlikely that it resulted from the overlay injection (despite the fact that that
should only directly affect PE code.)
