#1028 "a;" outside a module causes compiler to segfault

[Theodore Dubois]

This is on version 10.1, which I believe is the latest.

I am unable to reproduce this. The code

a;

results in the error message

-:1: error: variable declarations must be contained within a module.

The compiler used to segfault on this code, but this was fixed just before the v10.0 release (bug #992).

Can you provide a simple test case that demonstrates the fault you are seeing.

I am able to reproduce it on Mac on version 10.2, but not on Linux.

The difference appears to be the version of bison used at compile time. macOS includes bison 2.3, and building with that version causes the segfault. Building with bison 3.0.4 works fine.

I have added a note in the README file to alert users to the problem with bison 2.3.
