I see that both of the bug reports you are looking at are older than
this bug report and the change you bisected to. Are you sure you're
tracing the same error that those reports are about, or are you seeing
a new error due to the change to the new glpk API?

If the error you're seeing is something that used to work in 3.6.4,
then that should be marked as a regression.
