Franz is quite right it is. ===== It is a particularly nasty bug - because it is one of those where something drops bombs in memory. ==== The code generated by gcc 2.95.3-t2 is fine - from asm through to vmlinux. ===== However, every now and then - at run time - something trashes the location which throws up the Illegal Instruction. as I said - nasty - it could be *anything* and I'm not really sure how/where to start looking... much though I hate to admit it (being a firm believer in low-tech printk debugging) - this is one of those cases where an ICE would really triumph... ciao, Iain. ** Sent via the linuxppc-dev mail list.
