Memory Error #16

Closed mberry28 closed 6 years ago

mberry28 commented 6 years ago

Hello!

I recently spontaneously started getting this error listed below. I was making adjustments with a .UNIT file and it started to get this error. I can't seem to make it go away, even if I removed the UNIT file I was working with. It will run for several (more than 10) dt iterations then suddenly crash with this error.

I have restarted my machine, simplified my model, reinstalled TISC, cleared background RAM uses, and it seems to persist.

Any ideas?

tisc(64210,0x7fff75aec000) malloc: *** error for object 0x7fd3bac74f68: incorrect checksum for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6

I also should note, that I have spent some time Googling the solution and the error, but none of the solutions seem to work for this or it's outside my experience. I will keep toying with it and report back if I find a solution.

that seems a memory error and my usual valgrind is currently not working for mac, for some version issue. Otherwise i would ask you the input files and try reproducing it. I you don't use mac try running the memory checker "valgrind", it should give you the line of the memory leak.

As spontaneously as it seemed to start, the problem doesn't seem to be happening anymore. I am sure something changed, but I am not sure what it is.

BTW, Valgrind kept repeatedly having segmentation faults when using TISC, perhaps also a version issue?
