I've tried. No change. And that really sucks as I need to run the
debugger and I cannot do it normally ;(

stracing on gdb gives a constant loop of:
ptrace(PTRACE_PEEKTEXT, 7730, 0x401f5ccc, [0]) = 0
ptrace(PTRACE_PEEKTEXT, 7730, 0x401f5cd0, [0]) = 0
ptrace(PTRACE_PEEKTEXT, 7730, 0x401f5cd4, [0]) = 0
where the 3rd argument is rotating the last three hex numbers in the
loop. After a while gdb gives up and just hangs

Yeah, OK. Hope I will find some more deterministic way to do that :)
