But the weird part is, the result is not stable, out of 10 times testing, segmentation fault appear ~6 times. I run your example code but did not find any problem, it display mytestok. The last segmentation fault of "double free" is due to freeing of variables. ``` [ RUN ] MYTEST.Forward [total]Time difference = 58228[mu s] [avg]Time difference = 582[mu s] mytestok double free or corruption (!prev) Aborted (core dumped) ``` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
