Package: gcc-4.9

After trying different toolchain versions, for binutils and gcc-4.9, it builds 
with -O1, but fails with -O2. So, apparently the bug is on the GCC optimizer.

I was about to file a bug upstream for that one, but I was unable to reproduce 
with gcc-snapshot, therefore I file it here for now.

Find attached testcase: process.i

Compile line to be able to reproduce:
gcc -c -g -O2 -fstack-protector-strong -Wall -D_FORTIFY_SOURCE=2 -I. 
-DACORN_FTYPE_NFS -DWILD_STOP_AT_DIR -DLARGE_FILE_SUPPORT -DUNICODE_SUPPORT

-DUSE_BZIP2 -DIZ_HAVE_UXUIDGID -DNOMEMCPY -DNO_WORKING_ISPRINT process.i
