Crash at startup on MinGW 64 builds #1522
Description
OS: MINGW64_NT-10.0-22631 3.4.10.x86_64 2024-02-10 08:39 UTC x86_64 Msys
MLT: 7.22.0
Shotcut: 24.02.29
GCC: 13.2.0
MinGW 64 builds of Shotcut are crashing at startup when using MSYS2's MINGW64 environment.
Surprisingly this is only affecting GCC builds. The Clang builds in both CLANG64 and CLANGARM64 do not show this issue.
Steps to reproduce:
- Open the UCRT64 or MINGW64 environment in MSYS2
- Export
QSG_RHI_BACKEND=d3d11(This was done so gdb would attach to the right process) - Run shotcut.exe
Expected
- Shotcut launches correclty
Actual
- Shotcut crashes after briefly showing the splash screen
