While you have compiled with "-g" you still did not extract the
line number information. Did you strip (ld -s option) the executable?
If you have compiled with debugging support and not stripped,
you should receive a backtrace with line numbers in it.

Having said the above: the code in RAND_bytes does only access locations
allocated as static arrays, so I would be most surprised to see the problem
in RAND_bytes.
There is just one exception and that is the memory to which the random
bytes are written.
Please make sure that "buf" is pointing to a correct memory location and
is large enough to hold the number "num" of bytes requested.
As the software is nice enough to SEGV you can run it under the control
of the debugger and it should even jump to the offending location in
the source.
Sincere regards,
Lutz
