[Bug 42646] New: GdipDrawPath call raises " Invalid floating point operation." exception

https://bugs.winehq.org/show_bug.cgi?id=42646

            Bug ID: 42646
           Summary: GdipDrawPath call raises "Invalid floating point
                    operation." exception
           Product: Wine
           Version: 2.3
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gdiplus
          Assignee: wine-bugs(a)winehq.org
          Reporter: remk_1(a)yahoo.com

Testcase - Unzip and run under Wine to see the error

Applications calling GdipDrawPath function (part of gdiplus.dll) raise "Invalid
floating point operation." exception when the following two conditions are met:

- pen width used to draw the path is 1 (the shape is drawed correctly when the
pen is wider)
- the graphics object used to draw the shape is a bitmap (when it is drawn
directly on a form canvas without the temporary bitmap, there is no exception
raised)

  See the attached WineGdipBug.exe file that demonstrates the problem. I attach
also a very simple Delphi XE2 source code used to build the testcase.

  Under native Windows, the testcase application correctly displays simple form
with a rectangle drawn inside it.

  In wine-2.0 or higher, including wine-2.3, the application displays exception
window with a message "Invalid floating point operation." The message is shown
several times, whenever the form has to be repainted.

  In older Wine versions up to wine-1.9.9, the exceptions are not risen, but
the path rectangle was not drawn either. Shell windows shows a warning
"fixme:gdiplus:GdipDrawPath graphics object has no HDC", which is probably
related to the bug. Needless to say that the missing frame and warning was just
a little annoyance compared to the current Wine versions, that makes affected
applications almost unusable.

Tested at Fedora 24 and Ubuntu 16.04 LTS

I can confirm the exception in wine 2.7 but it is weird that if you run it
inside winedbg it will draw the rectangle and still show the exception.

winetricks gdiplus is a workaround.
