With gcc 4.2.3 I get the same error. The noinline patch fixes it again.

OK, so it's an unfixed bug in gcc, and it looks to be specific to the
alpha backend.

No, other architectures are just lucky that the compiler decides
a) not to generate a jump table for switch statement in sd_major() and/or
b) not to inline this function.

I have a similar test case that fails on x86 as well.

if the compiler chooses to inline a function, it has to
respect the sectional (and other constraints) of the outer function.
Can someone file a bug report with the relevant compiler people?

It would be good, but in the meantime the 'noinline' fix seems to be
a most sensible option...
