Hi List, Thierry,
Below script makes haproxy perform a coredump when a function that
doesnt loop forever is put into register_task.. is it possible to add
some safety checks around such calls.?.
The coredump does not seem to contain any useful info when read by gdb..
unkown functions at unkown addresses...
Also i tried to register a new second task inside the c==5 check, but
then it just seemed to hang..
Maybe not really important as people should probably never use a
function that can exit for a task.. , but its never nice to have
something perform a coredump..
Regards,
PiBa-NL (Pieter)
