[Debian-med-packaging] Bug#1004037: Segmentation fault in plink2 (Was: src:plink2: fails to migrate to testing for too long: autopkgtest regression)

[Chris Chang]

Hmm.  Ordinarily, that download link would be fine.  I had not updated it
this time because the issue only affects gcc 11+, so it did not affect any
of the precompiled binaries and I wanted to keep the posted source
identical to that used to compile those binaries.

On the other hand, the only difference (in the non-gcc-11+ case) between
the binaries and the updated source is the version date.  I guess this is
insignificant enough that a temporary discordance is less disruptive than
making you change your packing process, so I've updated the website source
link to point to the newer code; let me know if you still run into any
problems.
