Hi!
With gcc 2.95.2 targeting mingw32 from linux, this code:
/*--- xyz.cpp ---------------------------------------------------------------*/
#include "xyz.h"
#pragma implementation "foo"
#pragma interface "foo"
class two: public one {};
/*--- xyz.h -----------------------------------------------------------------*/
#pragma interface "bar"
class __declspec(dllimport) one {
public:
// virtual ~one(void); // see note
virtual void func(void);
} ;
/*---------------------------------------------------------------------------*/
gets me:
$ gcc xyz.cpp
xyz.cpp:6: Internal compiler error, output_operand_lossage `invalid
expression as operand'
If I use -fno-rtti, I have to uncomment the virtual destructor to get
the same behavior.
I know that this error message has come up on the list before, but I'm
pretty sure that this instance is an actual bug and not a result of
trying to do things that are impossible with imported DLL data --
because the above code is a snippet from the wxWindows cross-platform
GUI library, which compiles happily under several different windows
compilers. Or am I missing something obvious?
Am I doing something wrong? Is there a way to work around this? If
it's a bug, I'd be willing to take a stab at a patch if someone can
point me in the right direction.
thanks very much,
