The code seems to be trying to detect if ASLR is enabled and fails if so.  But if ASLR is the problem, then gdb's default disabling of ASLR is fine.  The problem would be if the user had done 'set disable-randomization off' to re-enable ASLR.  And then the solution is not to do that, or to do 'set disable-randomization on'.\r\n\r\nBut the problem here is that we get the fail even when not running under gdb and when ASLR is disabled system-wide (set /proc/sys/kernel/randomize_va_space to 0).\r\n\r\nJudging by the test, whichever library this is in has been loaded at 0x5xxxxxxx and for some reason that's a problem."}}
