I was going to ask if this is already upstream and if you had a reference to the upstream version control, but GNU bc doesn't seem to have any public vcs (or any real activity). I see the latest alpha release is from 2006, and that one does make save_adr static and NEWS contains the following note: Bug fixes: fixes bug in load_code introduced by mathlib string storage in 1.06. I personally don't use bc, but if people (and other distributions) think the 1.06.95 alpha version is better then lets use it. A quick look at the Debian package shows that they are carrying some patches that might be interesting, E.G. 03_array_initialize.diff seems like a clear bugfix: https://packages.debian.org/jessie/bc Care to send a patch to bump the version with this info?
