 wxSVN-Trunk last week, wxMSW, Visual Studio 2005

 I have a stack overflow as a result of an unterminated recursive call:
         wxbase290ud_vc_8_litwindow.dll!wxMBConv::MB2WC(wchar_t *
 outBuff=0x00000000, const char * inBuff=0x0102cb08, unsigned int outLen=0)
 Line 321 + 0x1a bytes      C++
         wxbase290ud_vc_8_litwindow.dll!wxMBConv::ToWChar(wchar_t *
 dst=0x00000000, unsigned int dstLen=0, const char * src=0x0102cb08,
 unsigned int srcLen=4294967295)  Line 211 + 0x15 bytes   C++
         wxbase290ud_vc_8_litwindow.dll!wxMBConv::MB2WC(wchar_t *
 outBuff=0x00000000, const char * inBuff=0x0102cb08, unsigned int outLen=0)
 Line 321 + 0x1a bytes      C++
         wxbase290ud_vc_8_litwindow.dll!wxMBConv::ToWChar(wchar_t *
 dst=0x00000000, unsigned int dstLen=0, const char * src=0x0102cb08,
 unsigned int srcLen=4294967295)  Line 211 + 0x15 bytes   C++

 strconv.cpp:321, Function MB2WC calls ToWChar
     size_t rc = ToWChar(outBuff, outLen, inBuff);

 ToWChar calls
         size_t lenChunk = MB2WC(NULL, src, 0);

 This happend after I choose 'Exit' to terminate my application.
 Unfortunately the Call Stack no longer shows the original calling
 function.

 strconv.cpp is of revision 53891

 Regards

 Hajo
