Hi,
Turns out that some fool (me) left a debugging trap enabled. ; - (
I'll put out a new release asap with that fixed.
If you'd like to make a tiny patch, replace this file in star/private.
Then in star/test do
./mk
./export
Sorry for the inconvenience.

For reference, the inlist_15_z2m2 is identical to mesa/start/test_suite/15_si_burn/inlist_15_z2m2 except this flag is changed and I do not load the test_suite model but rather start from pre-main sequence). I've also seen this occur in the same place in stars up to 19Msun.
