my daily CI of Coq Platform indicates that this update:

libgpg-error0-1.37-1 -> libgpg-error0-1.47-1
breaks Opam, the OCaml package manager, via a failed call to curl as can be seen
by executing these commands:
$ wget
https://github.com/fdopen/opam-repository-mingw/releases/download/0.0.0.2/opam64.tar.xz -O "opam64.tar.xz"
$ tar -xf "opam64.tar.xz"
$ bash opam64/install.sh --prefix "/usr/$(uname -m)-w64-mingw32/sys-root/mingw"
$ opam init --bare --shell-setup --enable-shell-hook --enable-completion
'default' 'https://opam.ocaml.org' --disable-sandboxing
Replacing the DLLs of libassuan0 and libgpg-error0 with the previous versions
listed above (just replace the DLLs) fixes this.
I had a look at what happens with Procmon. In the end a call to cygwn curl (from
a MinGW app) fails. In Procmon I can see that curl successfully downloads the
file and crashes immediately after closing the output file. With the old
versions of libassuan0 and libgpg-error0, curl succeeds. That this download as
such is successful shows that this is not a temporary network hickup (I also
tested it at least 10 times either way).
Usual usages of curl seem to work - I couldn't reduce the failure reproduction
beyond the above 4 lines and couldn't figure out what is so special about the
curl call of opam.
This is quite painful for me - I was in the middle of a release of Coq Platform
(a widely used distribution of the Coq proof assistant), when my Windows CI
(which does a cygwin based MinGW cross compilation of OCaml and Coq) failed.
Especially painful is that there is no easy way to install older package
versions from the command line.
I would appreciate a fast roll back. Otherwise I have to find a way to install
the older versions without user interaction.
I don't build curl, gsasl, or libgcrypt with libassuan, which is used by gnupg2
internally between components for IPC.
Deps are:
opam -> curl -> libcurl4 -> libgsasl18 -> libgcrypt20 -> libgpg-error0
I have not yet upgraded libgpg-error and rebuilt libgcrypt, gsasl, or curl, do
not use OCaML or Opam, or have them installed.
Btw.: I do a daily build test of Coq Platform with a fresh cygwin since about 6
years and this is only the fourth failure! I really appreciate the stability of
cygwin - excellent work!
