| Summary | 0000046: Jessie/GWhy/Gappa: format file and invalid POs proved valid | ||||||||
| Description | Hello, Under Cygwin, for the following code: /*@ requires -1.0 <= x <= 1.0; assigns \nothing; ensures -1.0 <= \result <= 1.0; */ float f(float x) { return ( -2.0*x ); } with command-line: frama-c -jessie-analysis -jessie-gui faux.c all POs are proved Valid under GWhy, even they are *not*! In GWhy's Debug mode, standard output displays: oblig : f_ensures_default_po_1 calling Gappa on c:\TEMP\gwhyd42d1e_why.gappa command line: gappa < c:\TEMP\gwhyd42d1e_why.gappa Output file c:\TEMP\outba8609: input in flex scanner failed ... Trying to prove the 1st PO through the following command line: gappa c:\TEMP\gwhyd42d1e_why.gappa yields: Error: syntax error, unexpected $undefined at line 1 column 27 1/ It seems that gappa files are expected to be in UNIX format, and not in DOS' one (i.e. with CR/LF ending lines). 2/ When gappa fails in achieving file parsing, GWhy seems to wrongly interpret it as proved Valid.

Once cpulimit-win replaced with its last version as mentionned in Bug-0049, point #2 presented here is solved. However, point #1 remains. For information, Gappa version used is 0.11.1. |

I have released Gappa 0.11.2, which should hopefully fix the eol issue. |
