I'm trying to apply frama-c/jessie on a module of a proprietary safety critical system from our customer. The function under analysis is pretty big (image 700 uncommented lines count) with a lot of conditional statements as well as complex (&&, ||, etc).

I got this error message when I ran it on Ubuntu VM 64 bit machine. It appears Error 137 is related to memory size, etc. But I'm not quite sure.

Any suggestion for how to approach this error is greatly appreciated.

with a lot of conditional statements as well as complex (&&, ||, etc).

You should use the so-called “fast WP” option when analyzing functions with lots of nested conditionals. Otherwise, the target does not even need to be very large to cause a blowup.

It happens to be the example in Jessie's manual for passing options to Why (it is really a Why option):

-jessie-why-opt=<s>
give an option to Why (e.g., -fast-wp)

You would therefore use -jessie-why-opt=-fast-wp.

  • Hi, Thanks. I tried with the -fast-wp on alt-ergo but got the following timeout :total : 1 valid : 0 ( 0%) invalid : 0 ( 0%) unknown : 0 ( 0%) timeout : 1 (100%) failure : 0 ( 0%) total wallclock time : 10 h 49 m 57 sec total CPU time : 5 h 32 m 11 sec valid VCs: average CPU time : -nan max CPU time : 0.00 invalid VCs: average CPU time : -nan max CPU time : 0.00 unknown VCs: average CPU time : -nan max CPU time : 0.00 – user3150318 Jan 04 '14 at 15:50
  • Is it possible at all to use Jessie on a function that has 600 uncommented lines with a lot of conditional statements? I always get timeout, unfortunately. May be there is a trick I am missing? – user3150318 Jan 07 '14 at 16:01
