[ANNOUNCEMENT] Updated: binutils-2.35.2-1, mingw64-{i686, x86_64}-binutils-2.35.2-1

[Achim Gratz]

The binutils packages for Cygwin and MingW64 cross-compilation
toolchains have been updated to the upstream bugfix release 2.35.2.

Since no new features have been added and the update contains security
fixes, no test period is applied.

The GNU Binutils are a collection of binary tools.  Most of these
programs use BFD, the Binary File Descriptor library, to do low-level
manipulation. Many of them also use the opcodes library to assemble and
disassemble machine instructions.

Random assembler errors after update mingw64-x86_64-binutils-2.35.2-1

[Michael Soegtrop]

Hi Achim,

I have some evidence that this update leads to random assembler errors. 
I have 3 CI failures (out of 5 runs) since the update in an open source 
project I maintain. The failure is always an error from the MinGW 64 
assembler and the errors are random - that is if I rerun the same CI 
test the error went away in one of one tested case and in the failing 
cases the error happened compiling different files.

I haven't seen anything like this before the update.

Here are links to one failing and one good case:

Fail run package version:
https://github.com/coq/platform/runs/1803203762?check_suite_focus=true#step:4:164

Fail run error message:
https://github.com/coq/platform/runs/1803203762?check_suite_focus=true#step:4:1664

Good run package version:
https://github.com/coq/platform/runs/1799374171?check_suite_focus=true#step:4:164

I will revert to the old version of the package and see if the errors go 
away.

The 32 bit version seems fine do far.

Best regards,

Michael

An update on this:

I reverted to the previous version of MinGW 64 binutils in our CI and 
didn't have issues since then.

Best regards,

Michael

Unless you have something I can reproduce I'm afraid there's nothing I
can do.  You can try reporting upstream to see if somebody else has seen
someting like that before or try bisecting.

None of them work for anybody who is not logged in to GitHub.

it can be a race that the current package is just exposing

a copy of the assembler file and original source could give some hint
