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.
