Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
The example is being developed from a kernel, so some operations may look
strange. However, the example is self-contained.
Platform:
Ubuntu 12.04 x86-64, all updated
Compiler:
Cross compiler as described here: http://wiki.osdev.org/GCC_Cross-Compiler
for i586-elf. Compiled for x86.
Error does not occur with standard GCC (this may be because the standard
GCC on the platform is x64-64).
