Package: gcc-4.0
Version: 4.0.3-1
Severity: normal
Linux kernels compiled with gcc 4.0.3 have invalid debuging information.
More information on this issue and how to verify this error can be
obtained in bug #378621. I'll also have to use gcc 4.0.3 to compile a
kernel with CONFIG_DEBUG_INFO, CONFIG_KPROBES, and optionally
CONFIG_RELAY. You also need the resulting kernel unstripped vmlinux.
Notice that bug 378621 was filed against systemtap but the issue here is
gcc 4.0. GCC 4.1 seems to provide correct/good debug information though.
Besides, although this error was spoted in a kernel compiled with 4.0,
this bug should also affect ordinary user-space debuggers.
