Sometimes I get crashes with the error "0x40010006 - DBG_PRINTEXCEPTION_C", only with 1.60, never had these crashes before.

Googling this error it sounds like OutputDebugString can cause it, https://maximumcrack.wordpress.com/2009/06/22/outputdebugstring-awesomeness/

"Internally, a debug string is handled as an exception. OutputDebugString calls RaiseException with DBG_PRINTEXCEPTION_C (defined as 0x40010006) and the string address and size as the exception parameters. To keep this transparent to the debugger, Windows effectively swallows the exception and notifies the debugger of it through the debug string notification."

Was some debug code accidentally left in for the 1.60 release? Or maybe the crash handler is catching things it shouldn't be?
