Could you check if this now works?Р”В®dit2: Note that the gdb backtrace is much more informative if you compile your own Python version as described earlier:Р”В¬ode: Select all #0 0x00007ffff640f418 in _GI_raise at.

I tracked this down to a bug in Python itself - in the PyArg_ParseTupleAndKeywords() function where the 'p' argument format is not correctly converted into a C bool type, and fixed it in the python/r9 branch. Meanwhile I would appreciate if someone could:Р”РЋ- Point out any tool that may help me to pinpoint where (I mean, in which statement) I am doing this stack smashing?Р”Сћ- Give me some clues that could help me speeding up the buggy statement identification in the code.I also see the smashed stack issue when I compile my own Python-3.5.2 version (edit: in my Ubuntu 16.04 VM). I am currently carefully checking each line of code, one by one, trying to find out the buggy statement.

#Mpi stack smashing detected c++ code

I tryed to detect the line in the source code where I could be smashing the stack with valgrind, but I arrived to the conclusion that it canР’Т‘t help me to debug my current stack smashing error (Reference: Go to the page below on wikipedia, and make a 'search in this page' for the 'stack smashing' gdb backtrace reports the error ocurred at the instruction that return from the main program, hence, curiously all the outputs from the program are done successfully but the program does not end normally as it abnormally terimnate with this bug (!!).

It has a dozen of functions and a main program. I would have pasted the code here but its approx 2000 lines. I am stuck for 1 week in a *** stack smashing detected *** bug in my C program running in a i386 desktop with Ubuntu 7.0.4. I hope to contribute during the posting and replies on this thread. I am sorry my first post here is a question.
