https://community.intel.com/t5/Software-Archive/Execution-error/m-p/987947#M27613 Help! Help! in dire straits!!!! Re: Large scientific simulation. I build both Debug and Release. From a DOS command line both executables run (execute). However, if I attempt to run the Debug in the windows developer environment it goes nowhere (not even allowed to break on the very 1st executable line) and immediately gives: "Instruction at 0x50c18522 referenced memory at 0x000000bc. Memory could not be read." Help, Help, help in dire straits!!!!

Restart Developer Studio. That should cure it.<BR /><BR />Steve Tue, 16 Apr 2002 21:43:09 GMT https://community.intel.com/t5/Software-Archive/Execution-error/m-p/987948#M27614 Steven_L_Intel1 2002-04-16T21:43:09Z
