Description

I'm unsure of the min requirements for it to happen, but at least for ruby embedded in a gui mingw32 application, enabling JIT causes a conhost.exe popup for every gcc call, repeatedly stealing focus.
The easy fix is to add the CREATE_NO_WINDOW flag to CreateChild calls in win32.c, line 1326 in particular.

(Only somewhat related: It'd probably help performance if a single conhost could be shared among gcc calls, instead of letting Windows make a new one for each.)
