I am using Ipopt with MUMPS through jIpopt on OS X. The version is
3.11.9.<br>
When using a specific (not too large) set of data with my model
using
<meta http-equiv="content-type" content="text/html; charset=utf-8">
metrotha-algorithm, I get a segmentation fault every time.<br>

There was a release 3.11.10 which mentioned a memory allocation bug,
but this does not seem to me like that.<br>
Both crashes seem to have something to do with smart pointers (see
the attached error logs for stack trace) and curiously both have the
same function (Journalist#printf,
_ZNK5Ipopt10Journalist6PrintfENS_13EJournalLevelENS_16EJournalCategoryEPKcz)
in callee-saved register.<br>
<br>
I would've reported this error in trac, but I seem to get this error
on every form submission there:

<br>
Do the stack traces point enough to correct direction, or would more
information be useful? I don't see an easy way to make this easily
reproduceable.<br>
