According to my Google research it looks more like a bug in binutils.

The attached patch from Richard Henderson claims to fix that.
(http://sources.redhat.com/ml/binutils/2003-04/msg00241.html and GCC PR 10326)

"This is caused by a long-standing bug in the GNU Linux-Alpha toolchain. 
Certain symbols (such as switch-related jump tables in inline C/C++ functions) 
cause gcc to emit object relocations leading to removed ELF sections."

Perhaps someone with an alpha likes to test it..
