Hi all,
When I compile the following program:

#include <stdio.h>
#include <string.h>

int main()
{
char x[100];
int len;

strcpy(x, "mumbo jumbo");
len = (int) strlen(x);
printf("%d\n", len);
return 0;
}

with icc 11.1 and optimization level -O2 or higher, valgrind complains about numerous runtime errors, most probably initially triggered triggered
inside strlen(). If, however, I compile it with '-nolib-inline', all error messages are gone.
Besides, compiling with icc 10.1 or 11.0 also gives no errors.

I hope that helps,
greetings,
Andreas




I'll take a look at this.  What command line are you using for valgrind?
