Thank you so much, Roland!
But this is really not the place to discuss arcane
implementation choices in glibc.
Sorry for posting the question in a wrong place... I thought that the
problem could have something to do with ptrace or with me using it
incorrectly. And I could not find any other
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
Thank you for the response, Roland!
Off hand, it seems more likely there is some authentic variation
between runs for whatever reason than that this has something to do with
ptrace.
I agree, it most likely has to do with the process itself. I am puzzled
because something as simple as "hello w
Hello everybody,
I noticed a very strange phenomenon - not sure if it's caused by ptrace,
but I cannot understand why is it happening...
Here is a simple example (the code is attached below): trace a very
simple process (even "Hello World!" will do) with PTRACE_SINGLESTEP and
count # of step
