[Lilypond-auto] [LilyIssues-auto] [testlilyissues:issues] Re: #4943 Manual page breaking causing assertion failure

[Auto mailings of changes to Lily Issues via Testlilyissues-auto]

So I think the fix was successful in bringing the behavior of Windows systems (and other 32bit x86 systems) close to that we experience with other systems.

That makes debugging such problems while on a different platform and finding fixes for them in future quite more likely.

Now Valentin has given an example that fails on both 32bit and 64bit x86 systems. Fixing that becomes now better in reach, but even though it perfectly fits the headline of this report (though not the committed patch), it's sort of buried in this issue. Maybe it makes sense to move this out into a fresh issue, now more amenable than fixing to previously?

Inline assembler fallback for _FPU_SETCW() missing in MINGW libraries

Issue 4943
As Issue 4943 on Windows compilation was triggered by
missing _FPU_SETCW() in the MINGW libraries, an alternate call to
initiate the X87 FPU setup as an inline-assembler command is added
- for MINGW 32 Bit compilation only.

So, it turns out this was easy to minimise the code. File is attached.
It's still ~70 bars but only one voice, which is the dynamics staff of a
piano score (without anything else), so it's only silent music.

"AutoPageBreaksOff" in the score block causes the exception failure.

I note some "insane spring distance" warnings.These don't happen in the
real thing.

Note: According to Phil H's own tests: "This started in 2.19.21. 2.19.20 is OK."

Update: an instance of this affects also non-Windows systems, see comment below.
