Description :
If the user defines a function "memset" with specifications, then the generated function will be called __e_acsl_memset. But there is already such a function in e_acsl_mmodel.c, so there is an error on linking. Example:
/*@ requires \valid(p) ; */ int memset(char *p) { return 123; }
int main() { char *s = "toto"; memset(s); return 0; }
When compiling and linking:
/tmp/ccRT0UnW.o: In function __e_acsl_memset': scratch.gen.c:(.text+0x14): multiple definition of __e_acsl_memset'
/tmp/cc8qdTOL.o:e_acsl_mmodel.c:(.text+0x2b): first defined here
