Can't compile using wxWidgets as DLL (v2.8.10)

Hi to all!
I tried to upgrade the wxmsw28_gl_gcc_custom.dll that I successfully built with wxWidgets-2.8.6 (following this topic
http://forums.wxwidgets.org/viewtopic.php?t=14007 ) using the new wxWidgets 2.8.10
I compiled the DLL using the commands:
set WXWIN=c:\wxWidgets-2.8.10
set path=c:\Dev-Cpp\bin;%path%
mingw32-make -f makefile.gcc BUILD=release MONOLITHIC=1 USE_OPENGL=1 RUNTIME_LIBS=static USE_RTTI=0 USE_EXCEPTIONS=1 SHARED=1
and I obtained the wxmsw28_gl_gcc_custom.dll, but when I launch an executable that is built relaying on the DLL I receive the following error:
The application failed to initialize properly (0xc0000005)
and this is the report on Vista Home Premium (same prob in XP):
Problem signature:

Please note that if I use the old dll everything works fine...

Thanx in advance for any suggestion

Have you rebuilt the application, it could be due to incompatabilty between the wxWidget library versions.

I re-tried to build the wxwidgets 2.8.6 and I obtained the same prob... may be the problem is the batch itself...

any suggestion is welcome

I found out that if I build the lib using the Mingw files from wxDevcpp 6.10.2 it works fine (with both wxwidgets 2.8.6 and 2.8.10), using the file from wxDevcpp7rc6 the wxmsw28_gcc_custom.dll do not work...
probably there is something in the mingw distributed with wxdevcpp7RC6 that is missing something....

IIRC 6.10.2 used MingW gcc 3.4.2 and 7.0 uses MingW gcc 3.4.5. I don't know if that is causing the problem (doesn't seem likely), but that's the only difference I can think of between them.

I found a similar issue related to mingw 3.4.5 ...
