Memory leak with ICU 72.1.0.2 (Windows 11 24H2) #152
Description
Hello,
We have a memory leak with ICU 72.1.0.2 on Windows 11 24H2. This doesn't happen with ICU 68.2.0.10 on Windows 11 23H2.
Here are the steps in a gui program with a File / Save As command:
- LoadLibrary('icuuc.dll')
- Get the addresses of u_init, u_cleanup, and u_setMemoryFunctions
- LoadLibrary ('icuin.dll'). This loads icu.dll too.
- Get the addresses of ucol_open, ucol_close, ucol_strcoll, and ucol_setAttribute
- Call u_setMemoryFunctions to set memory allocation functions
- Call u_init. The memory allocation functions are called
- Open a Save As dialog (GetSaveFileName, comdlg32.dll) and cancel
- Call u_cleanup (). This doesn't release memory allocated by u_init
- Call FreeLibray for icuin.dll. icu.dll is not unloaded and memory is not released
- Note that at this step if you haven't called GetSaveFileName, icu.dll is unloaded and the memory is released
- Call FreeLibrary for icuuc.dll. No change.
