[I'm one of the maintainers of ginac in Fedora] Hi, in recent release, GiNaC::matrix::inverse() const was inlined, which changes the ABI, and there were some other backwards-incompatible changes. See the abi diff report [1], and the bug report where this was discussed [2]. Was this intentional?

This is unfortunate, because the interface change requires a rebuild of all dependent packages, but what's worse, the fact that the so version was not changed means that dependent programs might crash instead of just failing to start. Please consider either reverting the abi-breaking changes and releasing 1.7.4, or bumping the so-version of the library (to 7.0.0 most likely) and releasing too… [1] [2] https://bugzilla.redhat.com/show_bug.cgi?id=1541187 Thanks, Zbyszek
