seems it sometime can run completely without segmentation fault Case bug. There are some invalid write access in this case. viewperf.c: line2210: The size passed to modelMemoryCalloc is 0, however modelMemoryCalloc still gets a NON-NULL pointer. Unfortunately, some datas will be written to the location given by this pointer (line11372) which maybe result in heap corruption. verified. we may need to forward this issue to spec.org |
