Why do I get a Segmentation Fault on 64 bit machines running MATLAB R14 SP1 or SP2 64bit?
Show older comments
MATLAB crashes with a Segmentation Fault on an AMD Opteron 64 bit machines and Intel EM64T machines running Redhat Enterprise Workstation 3.0. No matlab_crash_dump or hs_err files are created. No error message given other than "Segmentation Fault". MATLAB stopped working once the OS was updated from their website.
