| Steps To Reproduce | Create the file logic_assigns.c :
#include
int *var_ptr;
/*@
logic int *the_var = var_ptr;
*/
/*@
//assigns var_ptr; // Works
assigns the_var; // WP Crashes
*/
void function(){
var_ptr = NULL;
}
void main(){
function();
}
With the above file, run:
frama-c -cpp-command 'gcc -C -E -x c' -pp-annot -wp logic_assigns.c
and the following output is received:
[kernel] preprocessing with "gcc -C -E -x c -dD logic_assigns.c"
[wp] Running WP plugin...
[wp] Collecting axiomatic usage
[wp] warning: Missing RTE guards
[wp] failure: Non-assignable term (the_var{Pre})
[kernel] Current source was: logic_assigns.c:15
