compilation fails on GCC with internal compiler error

[bertsky]

I am having difficulties comiling pynini – run via pip install . in the git working directory of the current version (after building+installing OpenFST 1.7.5) or source tarball of upstream 2.1.2 (after building+installing OpenFST 1.7.9).

Unfortunately, I only get this when running in a vanilla Ubuntu 18.04 container within a CircleCI setup (which uses this makefile and is based on this Docker image). I cannot even reproduce this in a local Ubuntu 18.04 myself.

Here are the full logs:

• compiling 2.1.0 with GCC 7.4.0
• compiling 2.1.2 with GCC 7.4.0
• compiling 2.1.2 with GCC 7.5.0

Any help on how to approach this would be much appreciated.

I'll upgrade what's mirrored here to 2.1.2, though as you mention that is not expected to help. In the past when I've seen this is really is perfectly good C++ code that somehow blows the stack of the compiler.

I will assume this can be reproduced on certain platforms, but probably none of the ones I have sitting around.

Upgrade to 2.1.2 is complete

Going to close this from inactivity/can't replicate. CI build testing on Mac OS X and Linux is handled by Conda and that should detect this for most users, and also gets you around the need to build locally.
