I solved my issue in saving MED mesh.Error is caused by a reference to a
volatile address in GModelIO_MED.cpp (see
https://www.securecoding.cert.org/confluence/pages/viewpage.action?pageId=29032683
for more info). I attached the patch that solves reported error, I hope it's
useful.
Archlinux uses gcc 5.3. New Cxx11 default ABI highlighted the problem.Regards.
