../src/ian.c: In function `MyFunction':
../src/ian.c:9: Insn does not satisfy its constraints:
(insn 34 29 22 (set (reg:SI 10 sl)
        (mem:SI (label_ref 38) 0)) 1 {*movsi_insn} (nil)

Please submit a full bug report.
See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.
>How-To-Repeat:
use the gnu for arm compiler (target thumb-elf) (redhat/cygnus) and compile ian.c with the -fpic flag:

thumb-elf-gcc -v --save-temps -c -fpic -o ian.o ../src/ian.c
>Fix:
take out the -fpic flag, or modify the source somehow...
