Still happening but on a different file. Preprocessed source attached.



xgcc (GCC) 4.8.0 20121103 (experimental) [trunk revision 193124]



Short command to go with preprocessed source:







/home/joel/v850/tools/b-gcc-svn-avr-rtems4.11/./gcc/xgcc

-B/home/joel/v850/tools/b-gcc-svn-avr-rtems4.11/./gcc/ -mmcu=avr25  -Os 

-mcall-prologues  -Wall -fno-builtin  -g -O2 -c t.c



Fails similarly at -O2 and -Os. Works at -O0.

I see hundreds of spill fails riunning the test suite -- with AVR-Libc.  Some
months ago, 2 or 3 pathological test cases failes with spill fails.  Now there
are hundreds of fails for simple test cases...

Reducing importance. I don't know of anyone building toolchains with the avr
target and using newlib as the C library. The avr-rtems target should be tried,
though.
