Crash Bug: Planar Tracker in Corner Pin

Confirmed in: Fusion Studio 17.3.1 and Resolve Studio 17.3.1

Occurs On: macOS 11.5.2 and Windows 10 20H2 19042.1237

Bug details:
While experimenting with the Planar Tracker in Corner Pin mode I have come across a very regular crash bug related to adjusting the Corner Pin positions. In particular I have been setting the corner pin to fill the whole screen as a part of testing some other PTra stuff.

I'm not sure whether the crash is specific to having a whole-screen Corner Pin, or whether it's just caused by having a large area, or just the regular manipulation of the Corner Pin values.

Either way, I have a comp that crashes 100% of the time for me. Open the attached comp and view the Planar Tracker node (PtraCornerPinFGoBG) in a Viewer, and Fusion Studio will crash every time.

Likewise, copying the nodes into Resolve Studio will cause the same crash there.

The crash occurs in:
Code: Select all
Fusion::MergeSimpleOverFlt16Process(Fusion::Image*, Fusion::MergeData*, int) + 456
Changing the frame format to float32 instead changes this to: Fusion::MergeSimpleOverFlt32SSE2Process

Here's the stack trace of the crashed thread:

I'm still using 17.2.2, but I can at least add that this was not introduced in 17.3.1.

Seems to be fixed in 17.4, thank you.
