gdiplus trace

To clarify, you need to actually load some audio into Melodyne and then click
on the pitch tool button. The crash doesn't happen if all you have is a blank
canvas. Apparently it also doesn't happen with literally any audio either,
though I only realized this just now (a simple sine beep is not enough). I'm
attaching a test clip that reproduces the issue. I'm on Melodyne Assistant
4.2.4.001 (it should hopefully repro the same on the trial version, though I'm
using a licensed copy).

This is the backtrace:
Unhandled exception: page fault on read access to 0xffffffffffffffff in 64-bit
code (0x00007f56c17ac8fb).

And I'm attaching the log from an untouched wine master (well, as of a few days
ago), though AFAICT tracing gdiplus doesn't log the actual path points without
extra patching so I'm not sure how useful it will be.
