Well, ARM64 hung up, but didn't hit the assert, so maybe there's some
*other* issue running around.  Unfortunately gdb doesn't work to attach to
a process there (it gets confused with the ARM64 DLLs loaded in the
process).  And WinDbg can't load the symbols for a cygwin dll (cv2pdb
generally works pretty well for this, but it seems to be confused by the
split .dbg file for msys-2.0.dll).
