Bug #17008
closedJIT enabled on Windows can cause constant conhost pop-ups
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.)

I have my own MinGW environment, but I've never observed such a behavior. Could you provide at least one way to reproduce the issue? I don't know of any GUI mingw32 application embedding Ruby 2.6+.
