Dear Maintainer,

the current version of python3-swiglpk in stable and most likely also the
version currently in unstable (5.0.10-2+b2) suffers from a memory leak.
The problem has recently been fixed upstream:
https://github.com/opencobra/swiglpk/pull/105

Packageing the latest upstream version (5.0.12) should fix this problem.

Thanks for your work maintaining the optlang ecosystem.
It is much appreciated.

Best regards,
Harald
