I installed a software for computational physics Quantum Espresso, one, using intel compiler/libraries and another using gnu compiler/libraries. My gnu compiled code is working fine but the intel compiled code gives an error (attached, beginning and end shown). I was trying to get a traceback for the error using -g and -traceback flag in CFLAGS, F90FLAGS and FFLAGS but it still does not give the complete traceback. How can I debug the error? I mostly followed the instructions here for installation of the software: https://software.intel.com/en-us/articles/quantum-espresso-for-the-intel-xeon-phi-processor
*** Error in `cppp.x': double free or corruption (out): 0x0000000000b6d650 ***
======= Backtrace: =========
ffffffffff600000-ffffffffff601000 r-xp 00000000 00:00 0 [vsyscall]
This looks like a memory error in one of the system libraries, a memory corruption or double free, it is a freeing of pointer which has already been freed. The reason why you don't get a complete traceback is that you would have to compile also the system libraries with debug flags.
