Hello Sylvain,

[Sorry for the late answer, but I was kind of expecting that someone
using Frama-C on windows could provide more helpful hints]

No: this should contain the result of the cal to alt-ergo, i.e. something like

alt-ergo res/store_swap_post_1_po_ergo.why
Run File "res/store_swap_post_1_po_ergo.why", line 1178, characters
1-491:Valid (0.0760) (28)

In fact, I was going to suggest to use -wp-out directory (which stores
intermediate files in directory and does not destroy them afterwards),
precisely to this purpose.
The fact that these files are empty indicates indeed that the issue
lies in the call to alt-ergo itself (if this was earlier, the file
wouldn't even be produced).

Best regard

E tutto per oggi, a la prossima volta
