What is the GDB version you used? where did you get the binary?

Could you please show a complete self-contained example, including the
source and the compilation command line?  Also, please tell what
version of GCC you used.  I'd like to try to reproduce this on my
machine.

Did you try applying that patch, and if so, did the problem go away?

Personally, I don't think it's related at all, because SLASH_STRING
should not be used where an absolute file name is taken apart to look
for the directory and the basename.  Instead, GDB should use other
macros, such as IS_DIR_SEPARATOR (from include/filenames.h), which do
cater to Windows filenames.

SLASH_STRING is only used to _construct_ file names, and that is okay,
since the Windows file I/O APIs recognize both \ and / as separators.
