Bug in egcs-1.1 (reduced testcase included)(PPC)

[Franz Sirl <Franz dot Sirl-kernel at lauterbach dot com>]

Hi,

on powerpc-unknown-linux-gnu I got the following error with egcs-2.91.53
19980809:

dialog.i: In function `AddButtons':
dialog.i:65: internal error--insn does not satisfy its constraints:
(insn 324 97 325 (set (reg:SI 0 r0)
        (high:SI (symbol_ref:SI ("*.LC2")))) 395 {elf_high} (nil)
    (nil))
../../../egcs/gcc/toplev.c:1360: Internal compiler error in function
fatal_insn

while compiling the attached code with -O2. -fpic, -fPIC, -O1 or
-funroll-all-loops make the error go away.

Franz.
