Thanks for your response. Double checked. There doesn't seem to be a problem with the executable. attached are the disassembly of the ROI begin and end functions and the original code.
I have debugged with GDB and stepped over the m5 commands, they occur only once and in the correct sequence. all this was done on qemo, but when I run it in gem5 the problem reoccurs. (The ExecAll logs weigh 53G (compressed) and I could not read them.) Any ideas?
