there are at least 4 commits that have touched s_audio_jack.c since 0.45-5.
- 5ff6366a5ad030ccd83730a14dcadadce943c352
- ab33f9b23ecd2014ec89d43541b9e4d3c080a424
- 73362cc6a57d89337815023f1ffc4ee0adc1de55
- ffd1a20bc8972c84e164d2266960b5d35275e907

as a first try i would test each of them and see which hs introduced the
problem (and what was the purpose of the patch).

since Pd crashes, it should be easy to create an automated test whether
the problem is there or not - so you can let "git bisect" do all the
work of finding the problematic commit.
