SpecPriv is not actually running - in S state (interruptible sleep), might be waiting for something. Will look into it by checking where it is stuck and what value it is waiting for

5335eb4fcc: Fixed segfault due to ostream related object missing

The root cause is address collision, the reason is delete ptr is not recognized due to virtualization (devirt is insufficient). Thus, the address collision is the correct behavior.

Depend on #5

source/libparest/message_log.cc: 275 -> include/libparest/utilities.h: 42 The delete callsite is not devirtualized.

vgene commented 4 years ago

Close this issue since it's not a bug. Will revisit if #5 is solved.
