there is a really good software tool developed by the Fermilab DAQ group, called TRACE - 

https://github.com/art-daq/trace ,

It could be useful for debugging cases like this one. In short, TRACE instruments the code 
with the printouts which could be selectively turned on and off without recompiling the executable. 

TRACE output could go to /dev/stdout (slow output) and/or to a circular buffer implemented via a shared 
memory segment (fast output). Sending unlimited output to the shared memory segment is extremely useful.

TRACE also allows to trigger on certain conditions, again, w/o recompiling the executable. 
For debugging cases like the one in question, that could turn out even more useful, 
however I didn't try the triggering functionality myself.
