I am not a usetex user, but in testing mpl on a linux box I got a new
error for dvipng. I hadn't seen this on this box before (it used to
work there) but I am not suspecting an mpl bug at this point, rather a
bug on the system. I don't really know, but others have reported
similar dvipng bugs unrelated to mpl on ubuntu so I suspect the
problem lies there. I am posting it here as a warning to others, and
also in case anyone has any idea how to fix, debug or diagnose it. I
would like to fix it because this is my primary machine for building
and testing and updating the docs, so I'd like to have usetex working.
If you google
glibc detected *** dvipng: free(): invalid pointer
there are a number of but reports
And now the bug, using the mpl 1.0.0 release
