Unlike solaris, this program demonstrates that glibc has issues resolving
symbols to data elements. I've tried it with glibc 2.0.7 and 2.1.2, both
with and without x being initialized:
void *handle = dlopen(NULL, RTLD_NOW);
int *symbol = (int*)dlsym(handle, "x");
char *errmsg = dlerror();
printf("error: %s\n", errmsg);
Actually, it seems unable to locate any local symbols.. main, or if I add
another function it can't look up that one either. It seems that
dlopen(NULL,blah) is what's broken possibly.

Yepp, this is a bug.
Oops, not really a bug. You need to pass -rdynamic at the link time to have this
fucntionality (you need to be able to access your own proram space like a shared
