Regression test for the DLL CRT initialization fix. Loads ghostty.dll at runtime and calls ghostty_info + ghostty_init to verify the MSVC C runtime is properly initialized.

Build

First build ghostty.dll, then compile the test:

zig build -Dapp-runtime=none -Demit-exe=false
zig cc test_dll_init.c -o test_dll_init.exe -target native-native-msvc

Run

From this directory:

copy ..\..\zig-out\lib\ghostty.dll . && test_dll_init.exe

Expected output (after the CRT fix):

ghostty_info: <version string>

The ghostty_info call verifies the DLL loads and the CRT is initialized. Before the fix, loading the DLL would crash with "access violation writing 0x0000000000000024".
