Thanks for the patch which I applied to packaging Git.  I assume you
want to express that while these fixes are definitely good coding
practice the bus error problem is not fixed by it, right?

Thanks, Andreas. It may fix the bus error, but I don’t have a MIPS machine to test on. Some of those logging calls had the potential to leave you with a misaligned stack pointer. IIUC unaligned loads on MIPS could cause such a bus error.
