[Kaveh R. Ghazi]

Snapshot:		egcs-CVS19981129
Platform:		sparc-sun-sunos4.1.4
Stage1 compiler:	cc
Assembler:		native
Linker:			native
BOOT_CFLAGS:		-g -O2 -D__USE_FIXED_PROTOTYPES__ -pipe

	I get the following failure building egcs, (after the three
stage bootstrap when it compiles libstdc++):

	Here is the backtrace from gdb.  Variable `insn' has the value 0x3.
Note, this only happens on SunOS4, not Solaris2.5.

	If there is any other info I can provide, (e.g. the preprocessed
source, 96K) please let me know.
