Have somebody tried GDB commands 'info float' and 'info reg' on a system
running latest ac kernels. I'm getting coredump from gdb-5.0 on these commands.
2.4.0-test1 - seems that all works, no such problem
2.4.0-test1-ac4 and 2.4.0-test1-ac7 - gdb coredumps on these commands
It seems to be some stack corruption.
