Preprocessed *.i* file that triggers the bug. See command line in description
to trigger bug.
Using GCC 4.6.3 on Debian armhf to create ARMv6+VFP binaries for Raspberry Pi
computer. The compiler differs from the standard Debian Wheezy armhf as the
configured with the options: --with-arch=armv6 --with-float=hard --with-fpu=vfp
The file that triggers the error mg.c from a build of the Perl package. Test
files and information to reproduce the error given below.
