@vouillon, I wonder if the CI is having the same issue I had with binaryen on windows in ocsigen/js_of_ocaml#1797 (comment)

[vouillon]

It seems that the errors means that either wasm-merge.exe or one of the dynamic libraries it depends on is not found.

I can retry locally at some point later.

Trying to debug this a bit in VS, I get libgcc_s_seh-1.dll not found..

Shouldn't this library come with conf-mingw-w64-g++-x86_64?

I don't know, I don't have such issue with the official windows binary release, maybe they don't use cygwin. @dra27, any idea ? Do we need additional setup ?

[vouillon]

They use Visual Studio. But I don't think we can expect all OCaml Windows users to have Visual Studio installed.

Oh, I meant conf-mingw-w64-gcc-x86_64 above. We install conf-mingw-w64-g++-x86_64 (which depends on it) to build wasm-merge.exe I can see the library in the Cygwin package file list: https://cygwin.com/packages/x86_64/mingw64-x86_64-gcc-core/mingw64-x86_64-gcc-core-12.4.0-1. Do you have mingw64-x86_64-gcc-core installed?
