If you have this code:

#include <stdio.h>

void test1(int) __attribute__ ((always_inline));
void test2(int) __attribute__ ((always_inline));

void test2(int b) {
    printf("test2(%d)\n", b);
}

void test1(int a) {
    printf("test1(%d)\n",  a);
    test2(a+1);
}

int main() {
    test2(42);
    test1(23);
}

And you put a breakpoint in test2, it will get hit first with the value b=42,
and then again with the value b=24.  If you're at the 2nd hit of the breakpoint
and you try to print the value of b, it says the name is ambiguous (presumably
because it can't decide between the first and the second b).
