Hi Roland,
I followed your advice and looked at the registers. Here is what I found:
The function that behaves inconsistently is _dl_start in ld-2.8.so. Most
of the time the first variation in the flow occurs as early as 296
instructions down the road, namely at the jump
30b3b0: 0f 86 d7 fd ff ff jbe 30b18d <_dl_start+0x22d>
but sometimes later. ( I am attaching disassembled _dl_start). And yes,
the registers do differ at this point, but so they should, considering
all these "rdtsc" - or am I missing something?
Thanks!
Roni.
