JIT: Unexpected behavior when running FPU apps

[midwan]

Hi Tom,

We tracked down an issue related to the current JIT code, which would need your help.
Here are the steps to recreate it:

• Get the RNOPDF app from Aminet (https://aminet.net/package/gfx/show/RNOPDF_OS3).
• Boot into a Workbench environment with JIT/JIT FPU enabled. The OS version doesn't seem to matter.
• Running the 68k (non-FPU) version of the app, works as expected. The application window opens up and waits for further input from the user.
• Running the FPU version of the app however, shows a "Stack overflow" error and fails to start.
• Disabling JIT and trying the same, works as expected (but of course, much slower).

The same tests on WinUAE work without the stack overflow error. ;)

Hope this helps, but let me know if I can provide anything more to assist further in tracking this down.

Unable to reproduce because of missing library (cybergraphics.library).

I didn't notice that, but you can just use the freely available P96 package from Aminet then, to get RTG installed. In my tests I was always using RTG.
