Thanks Guillaume for sharing the link, it helps me. Yesterday I have
posted the issue on wxWidgets forum and got the response that we have a
wxFont instance
as global or static variable somewhere in the code. Then I found wxFont
instance as static variable in *"hdFontAttribute.h"*. I have modified the
code and try to fix
the crash, it works for me.

Attached is the patch file contains the fix. Please review it and If
solution looks appropriate, then can you please commit it.
