MSYS2 has this patch [1]. Should it be incorporated by GCC somehow?

I think more interesting than the build.log would be preprocessed source it
ICEs on, so that it can be (attempted to) reproduced with cross-compilers too.

Did you reproduce the ICE when cross-compiling?
I suspect no, as the MSYS2 patch contains some twiddling about stack limits and
forces static linking of libgcc during bootstrapping, which should not affect
cross-compiling.

--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Of course not, I don't have any libraries/headers for that.
What I meant is if you upload preprocessed source, one might try to reproduce
it with a cross that doesn't have anything (binutils, libraries, headers), just
by trying ./cc1 ...

I didn't keep a copy of the file. It was stage1 xgcc that ICEs, not the host
gcc.

Today I got the same ICE when building mingw-w64. I am not clear why this error
only happened with GCC previously.

I received this response from MSYS2 later:
```
jeremyd2019 @jeremyd2019 Oct 26 10:52
how is that back?!?
that is caused by a messed up libgmp, and gcc segfaults when it tries to parse
a floating point constant
(specifically, a messed up libgmp import library, and used via mpfr)
gmp patch I sent upstream:
https://gmplib.org/list-archives/gmp-bugs/2020-October/004890.html
```
There's a detailed explanation about the cause in the mail linked above, which
also answers why this ICE does not always happen.
AFAICT this can be closed.
