Inadequacy/bug in gcc. The assembly it generates does not cope with large
functions. The easiest fix is probably to split the function up in the
source. The more tedious, but potentially more straightforward fix is to
compile with -S, manually hack the branches in the assembly, and then
assemble. I've done both - they both work.
