System: NetBSD shark1 1.3K NetBSD 1.3K (SHARK) #22: Mon Mar 29 11:14:23 BST 1999 rearnsha@shark1:/work/rearnsha/netbsd/sys/arch/arm32/compile/SHARK arm32


>Description:
	Trying to compile kdelib from the packages tree using a kernel 
	supped from yesterdays sources (plus Bill Sommerfeld's vm_machdep.c 
	patch) I got a bogus internal compiler error while compiling 
	addressbook.cc.  On trying to repeat the compile the kernel panics
	in pmap_handled_emulation.  Stack backtrace shows

		panic: pmap_handled_emulation: bogus read fault

		_panic(...)
		_pmap_handled_emulation(...)
		_data_abort_handler(...)

>How-To-Repeat:
	Try to build kdelib on a shark with the latest kernel (32MB memory,
	local disk)
>Fix:
