This looks like the patch is trying to create a data structure in a
memory context that's not sufficiently long-lived for the use of the
structure. If you do this in a non-cassert build, it will seem to
work, some of the time, if the memory in question happens to not
get reallocated to something else.

A good rule of thumb is to never do code development in a non-cassert
build. You're just setting yourself up for failure.
