Esy issue

[anchpop]

When adding @opam/dune-deps to my package.json devDependencies, I get this error:

info esy 0.6.11 (using package.json)
info building @opam/dune-deps@opam:1.3.0@53c75e19
error: build failed with exit code: 125
  build log:

    esy-build-package: internal error, uncaught exception:

This is probably an esy bug, but I thought I'd let you know about it too

I vaguely got the issue
the build path for dune-deps on my machine is ~/.esy/3/b/opam__s__dune_deps-opam__c__1.3.0-1c308da1
when I cd into that directory and run tree . the tree keeps on running infinitely maybe some cycle via smylinks (not sure)
so in esy there is this link https://github.com/esy/esy/blob/master/esy-build-package/Build.re#L423
which tries to delete the build path & goes in cycle

in the test directory there are two symlinks that are forming a cycle
link-to-foo -> https://github.com/mjambon/dune-deps/blob/master/test/proj/link-to-foo
link-to-parent -> https://github.com/mjambon/dune-deps/blob/master/test/proj/foo/link-to-parent

will look into this issue in detail & get back

Thanks for looking into it, I'd really like to use this in my project
