I assume the problem is not with exec-shield itself, but with address space
randomization.  There is a way to turn this on/off for all
children spawned from a process via personality, but it is on IA-32 only
ATM.  Once there is some way to turn randomization off on all architectures,
IMHO the GCC driver and GDB should turn randomization off (in the latter
case only by default, with possibility to override if needed).
