The standard advice when mcsema fails with bin_descend is to try using it with IDA. Can you name the specific binary you're trying to recover?

It was the donfos binary in the HackIM contest:

Any suggestion on how to add the isoc99_scanf into the std defs file?

I took a quickly googled for the prototypes of isoc99_scanf: http://www.ic.unicamp.br/~islene/2s2008-mo806/libc/stdio-common/isoc99_scanf.c and scanf: http://www.tutorialspoint.com/c_standard_library/c_function_scanf.htm and they are the same. We've also already got a different named version of the function here: https://github.com/trailofbits/mcsema/blob/master/mc-sema/std_defs/std_defs.txt#L774
My suggestion: copy that line, rename the function, and submit a commit / pull request ;-)

Cool! I'll make sure that a ton of new standard definitions are added to the next big feature push.
