minimal reproducible example

After Wine 7.16, setting a long window title leads crashes.
I debugged this issue and created a minimum reproducible example.

Steps to reproduce:
 1. Using winecfg, enable "Emulate a virtual desktop" or uncheck "Allow the
window manager to decorate the windows".
 2. Compile attached source file, e.g.
    % x86_64-w64-mingw32-gcc -o set_long_win_title.exe set_long_win_title.c
-lgdi32
 3. Launch the program with wine, i.e. wine set_long_win_title.exe
 4. Click inside the window.

Expected result:
 The window title changes to "xxxxxx..." (a string of 179 x's).

Actual result:
 It crashes with the following message:
 011c:err:virtual:virtual_setup_exception stack overflow 1808 bytes in thread
011c addr 0x7fae1e3a0a8c stack 0x4608f0 (0x460000-0x461000-0x660000)
