Some progress: after much debugging, David Rowe noticed that at least
one source of problems is the following code from oslec/oslec_wrap.c:
static __inline__ uint64_t cycles(void) {
uint64_t x;
__asm__ volatile ("rdtsc\n\t" : "=A" (x));
return x;
}
This seems to cause harm on amd64. Is this a problem with AMD? with x86_64?
