This does not seem to be happening. Part of the problem may be (and I am out of my depth here) that the fortran rtl library (ifort) does not appear to be dying prematurely, at least there is no signal that I can catch (I'm not a good c programmer). I posted to the Intel ifort site as well, and the response I got (see link below) is that "There is a feature request in to add this functionality, but it is not currently on the list for implementation." http://software.intel.com/en-us/forums/showthread.php?t=71571&o=d&s=lr > -- > Jeff Squyres > jsquy...@cisco.com - Laurence Marks Department of Materials Science and Engineering MSE Rm 2036 Cook Hall 2220 N Campus Drive Northwestern University Evanston, IL 60208, USA Tel: (847) 491-3996 Fax: (847) 491-7820 Web: www.numis.northwestern.edu Chair, Commission on Electron Crystallography of IUCR www.numis.northwestern.edu/ Electron crystallography is the branch of science that uses electron scattering and imaging to study the structure of matter.
