Dmc.exe hangs waiting on scppn.exe

Code was compiling fine until today (no changes). Did a final compile before sharing code. Now the compile hangs.

Updated QSpice. No joy. Uninstalled, reinstalled. Warm and cold reboots. Still no joy. Researched. scppn.exe is a DMC-specific thing. No obvious solutions.

FWIW, code compiles fine with MSVC.

Any ideas?

Found the problem. Apparently, DMC has some problem with explicit initialization of a pointer at global scope.

Absolutely minimal code demonstrating issue:
DMC_Bug.cpp (297 Bytes)

After running the buggy version, you’ll need to kill the process tree for scppn.exe in Task Manager.
