# I must not crash.  Uncertainty is the mind-killer. Exceptions are the
# little-death that brings total obliteration.  I will fully express my cases. 
# Execution will pass over me and through me.  And when it has gone past, I
# will unwind the stack along its path.  Where the cases are handled there will
# be nothing.  Only I will remain.

@nojb did you encounter this before?

[ghost]

@rgrinberg this was fixed in ocaml/dune#4249

[rgrinberg]

We'll release 2.8.4 with the additional fix.

[mseri]

Should we close this in favour of 2.8.4?

[rgrinberg]

Sounds good to me

[mseri]

Perfect, thanks. In the meantime the other PR was also merged
