We have observed crash on consumer daemon, during repetitive restarts of our trace generating system (target).
Crash is observed during the startup of the system. Reason for the crash is "double free or corruption (out)".

Below is the call trace from the core dump generated:
#0 0x000000804ce20000 in __GI_raise (sig=<optimized out>) at ../sysdeps/unix/sysv/linux/raise.c:55
