System: NetBSD buzzard.buzzard.freeserve.co.uk 1.5I NetBSD 1.5I (BUZZARD) #216: Sun Nov 19 21:24:48 GMT 2000 rearnsha@buzzard.buzzard.freeserve.co.uk:/usr/src/sys/arch/arm32/compile/BUZZARD arm32


>Description:

	gcc can miscompile some switch tables on the ARM due to the way that 
	the switch statement is represented internally.
	
>How-To-Repeat:
	Try to compile the gen* programs of the latest gcc at -O2: they then
	produce incorrect output and the resulting compiler crashes.
	
>Fix:

	The patch below has been extracted from gcc-2.95.2
