[Mingw-users] DlgDirListComboBox fails with MinGW 1.1

[Jaroslav S. <jar...@ya...>]

Hi all!
The following simple program lists the contents of the current
directory in a combo box. But compiled with MinGW 1.1 it fails on
DlgDirListComboBox win32-api call and generates an exception (access
violation). Compiled in lcc-win32 it runs correctly. Isn't it a bug in
MinGW 1.1?
I work on Win2000 and only the basic switches -c -Wall for compiler and
-s -mwindows for linker are used.
Can anyone help, please?
