Probably harmless, but if you figure it out please send me a patch.
Basically the steps are:
- find out which ioctl it is.
- check its arguments. if the arguments are 64bit clean (see
http://www.firstfloor.org/~andi/writing-ioctl32 for a definition) you just

If not you have to write a conversion handler, also following the tutorial

It works with the SuSE 32bit gdb/userland.
I think RedHat has a different libpthread. I don't have a RedHat userland,
so someone else will have to debug it.
