Re: v2.26.0 fails to start with return code -1073741569 (0xC00000FD)

Hi Steve,
sorry for not replying earlier.
Great that you managed do get a backtrace.
The backtrace points to a problem within Guile, the Scheme interpreter
Lilypond is built upon.

We currently do not release Lilypond for Windows ARM, because
setting up the compilation environment is far from being trivial
and the Windows support in Guile (speaking about x86_64) is buggy and fixe=
s
get upstreamed very slowly. AFAICT, no one is working on Windows ARM
support for Guile at the moment.

That said, x86_64 Guile should run in the emulation layer and it
should be possible to find out why it does not.
Unfortunately I currently have very little time to help you.
What I would like to do is sending you a self-contained Guile executable
compiled against the newer Windows C runtime (UCRT) to see
if the problem persists and/or verify that the problem is not a subtle
issue within the Lilypond-Guile interface.

Not sure when I will manage to do this, though.

Michael
