Segmentation fault #40

In running opam publish submit ./ocephes.0.8.1/ I've run into a segfault. Running the opam-publish command directly in lldb (I've only tested on osx) I get the following stack trace:

opam switch is 4.03.0. opam publish version is 0.3.1. Let me know if there's any other information I can provide.

rleonid commented 8 years ago

Unable to replicated with 4.02.3.

dsheets commented 8 years ago

Is this 4.03.0 vanilla or 4.03.0+flambda? mjambon/atdgen#45 may be relevant.

rleonid commented 8 years ago

Vanilla 4.03.0

rleonid commented 8 years ago

Still experiencing this problem with latest attempt to publish the same library.

I have the same issue here, with slightly different backtrace:

Fixed after updating atdgen so I think this can be closed.
