[mesa-users] MESA: doing something more than reporting...

[Bill Paxton]

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.
