The attached one line patch increases a local buffer size to

not ordinary bootstrap).
An arguably better solution would be to explicitly constrain
the range of the integer variable to that of valid priority values.
Unfortunately, as pointed out in bug 77721, due to the limitation
of the current VRP implementation, this isn't always reliable.

OK.
WRT 77721, could you add that test to the testsuite, but xfailed?
Sure. Done in r240595.
