backtrace is empty from usefull info

Hi all,

I'm running a large MPI job of the WRF model application (720 cores), compiled using Intel 2015u1 (15.0.1) and the MVAPICH2 MPI library.

When compiling in debug mode I'm using the following switches :

-g -O0 -fno-inline -no-ip -traceback -fpe0 -check noarg_temp_created,bounds,format,output_conversion,pointers,uninit -ftrapuv -unroll0 -u

I'm running until I have an exception overflow : error (72): floating overflow

However, the traceback of the output file form the specific core is empty with no useful info.

Any ideas on how to proceed in locating the problematic specific line of code ?

Thank you,

Jacob
