yes that temp is huge. my original error takes several hours to
get. so this test case is a much smaller pdb and mtz file.
at normal temp the error doesn't happen. but at high temp
it is the same behaviour as my large original data set.
and at high temp it doesn't crash in 1.5 but does crash in 1.6
