Summary0001026: value analysis memory consumption problem when using -lib-entry option
DescriptionWhen calling the value analysis with the -lib-entry option, on a program declaring a big static array, the computation of the initial state consumes an huge amount of memory (Out of memory exception likely).

For instance, try

frama-c -lib-entry -main f ./f.c -val

on

char mem[100000000];

int f(int x) {
  return x;
}
