ADD_FCFLAGS="-openmp" to configure and recompiling from scratch
fix things?<br>
<br>
If not, is it possible to supply me with a copy of your code so I
can attempt to reproduce the problem? I can't recall whether the
Ipopt driver shipped with the option to dump matrices, but if it
did a matrix dump of iteration zero might be easier?<br>

<div dir="ltr">Dear Ipopt Community,
<div><br>
</div>
<div>I'm attempting to run Ipopt-3.11.0 with the parallel
HSL solvers (<a href="http://www.hsl.rl.ac.uk/ipopt/" target="_blank">http://www.hsl.rl.ac.uk/ipopt/</a>)
on 64-bit Linux with Intel's compilers (version 13.1.1
20130313), but I encounter a segfault if I execute Ipopt
with MA86 or MA97 with OpenMP enabled. I am configuring
Ipopt with:</div>
<div><br>
</div>
<div>../configure CXX=icpc CC=icc F77=ifort
ADD_CFLAGS=-openmp ADD_FFLAGS=-openmp
ADD_CXXFLAGS=-openmp --with-blas="-L$MKLROOT/lib
-lmkl_intel_lp64 -lmkl_sequential -lmkl_core"</div>
<div>
<br>
</div>
<div>I am building the HSL libraries with Ipopt as
described in the documentation (that is copying coinhsl
into ThirdParty/HSL). </div>
<div><br>
</div>
<div>If I then modify the C++ test example hs071_main.cpp
to use ma97 (e.g. app->Options()->SetStringValue(
<span>"linear_solver"</span>, <span>"ma97"</span> )),
build, and execute, the code segfaults in
hsl_mc78_integer_mp_mc78_col_counts_integer_ (backtrace
included below). This same example runs fine with ma27,
ma57, and mumps. </div>
<div><br>
</div>
<div>Any thoughts, tips, tricks, or suggestions as to the
cause of this segfault? </div>
<div><br>

<div>Thanks, I'm happy to run more tests or provide more
details!</div>
