It seems like this is a problem with avr-gcc 4.4.1, which some people are using 
in Linux.  It works under 4.3.2, 
which is included with the Mac and Windows versions of Arduino 0017.

This issue also seems to keep the LCD library from working. (confirmed 4.3.2 
GCC on a 
mac works.... 4.4.2 on Fedora 12 does not.)

I'm having this issue as well with gcc 4.5.0.

Confirmed, under avr-gcc 4.4.2 on fc12 it doesn't work. avr-gcc 4.3.2 and 4.3.3 
DOES
work on fc12. No problems with arduino-0017 on windows xp through.

Has anyone tried with avr-gcc 4.4.4?

It seems like this is a bug in avr-gcc and since I haven't seen any suggestions 
for workarounds that I can do in the Arduino source, I'm marking this as won't 
fix.  I'm hoping that the Linux package maintainers will patch avr-gcc instead.

Here's a possible workaround:

Fixed by itself with newer avr-gcc
