Description :
Running "frama-c -val ftest.c" on the attached program reports an unsatisfied precondition in line 4, where \valid has been applied to a pointer to the function foo().
From that behavior, I guess that \valid mustn't be applied to function pointers in general.
However, the acsl manual (acsl.pdf) says on p.54: "\valid applies to a set of terms (see Section 2.3.4) of some pointer type."
An apprioriate restriction to non-function-pointers could be added here.
