Package: gcc-4.9 Version: 4.9.1-16 Severity: important Hello,
Found a FTBFS while trying to build unzip package in Debian/sid on armhf host.

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.
