I was wrong. It's not GCC bug. "GCC guys" told that problem is in l4sys
Please see file:
here l4_ipc_send_tag() misses "memory" constraint in clobber list.
It definitely must have one.
Please fix it.
At the same time following file contains correct l4_ipc_send_tag()
So i guess the bug is just oversight. Anyway I think it's wise to look
through l4sys for similar errors.
