Description
While building cbc using the coinbrew script, I get a crash

### Running Cgl unit test

terminate called after throwing an instance of 'CoinError'
make[1]: *** [Makefile:621: test] Aborted
Further investigation shows that it's in the test in the title:
$ cd build/Cgl/master/test
$ ./unitTest

Commenting out the test in question lets everything pass. This is on an up to date Gentoo Linux, x86_64.
gcc version 15.2.1 20251018 (Gentoo 15.2.1_p20251018 p1). config.log attached:
I'd be happy to debug this for you if I knew how. (Building with particular options to get more info?)
