Description :
WP crashes when using a statement defined with 'logic'
Steps To Reproduce :
Create the file logic_assigns.c : #include <stddef.h>
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...
