Yeah :-(. The fact that we've not seen a similar failure on any other
machines points in that direction, too. Maybe it's some other aspect
of the machine's toolchain, like flex or bison, but that's not that
much different from our standpoint.
There's a lot of stuff I don't especially like about jsonpath_scan,
for instance I think the "init" arguments to resizeString etc are
a pretty error-prone and unmaintainable way to do things. But
I don't see anything that looks like it'd be a portability hazard
that would explain this.
I still have a nagging feeling that there's a wild store somewhere
in here, but I don't know how to find it based on the limited
evidence we've got.
