Bug #: 52773
Summary: internal error: in replace_pseudos_in, at
reload1.c:577
Classification: Unclassified
Product: gcc
Version: 4.7.0

An excerpt from SGDK v0.90 that demonstrates the bug
Using m68k-elf-gcc 4.7.0 with
m68k-elf-gcc -c -m68000 -Wall -O2 -funroll-loops -fomit-frame-pointer
-fno-builtin-memset -fno-builtin-memcpy bug.c
The problem disappears without -funroll-loops parameter (or -O0).
I was able to compile the code on my host machine (x86_64, gcc 4.6.3) without
any problems.
More details on the cross compiler:
m68k-elf-gcc -v
Using built-in specs.
