[mesa-users] "str_to_vector failed" when reading in saved model

[Earl Bellinger]

Hi mesa-users,

I'm using the new version of mesa (r8118). I just encountered a
peculiar error. I made a PMS model, evolved it to ZAMS, saved it and
terminated the evolution, then restarted it, and encountered the
following error:

I've attached the inlist and ZAMS model. I've done this same procedure
for many other tracks without encountering this problem. There's
nothing too peculiar about this track:

M = 0.927197
Y = 0.325059
Z = 0.009593

with everything else being standard (simple photosphere on the PMS, no
diffusion, no overshooting).

Any ideas?
