egcs-1.1.1 compiling glibc-2.1 with -O99 -fomit-frame-pointer

[Stanislav Brabec <utx@k332.feld.cvut.cz>]

Hallo egcs and glibc developers:

I have found following bug in egcs-1.1.1 when compiling glibc-2.1:

egcs-2.91.60

glibc-2.0.106/110
Bug in compiling ld-linux.so in elf directory when --enable-omitfp (-O99 -fomit-frame-pointer) is on.
This bug is visible by segfault during make on first call of ld-linux.so.
But both gcc-2.8.1 and egcs-1.1.1 when compiling 1.0.110 will fail on zic (see below).

Without --enable-omitfp egcs-2.91.60 compiles ld-linux.so OK, also gcc-2.8.1 with
--enable-omitfp compiles glibc OK.

egcs options:
configure --prefix=/usr --enable-shared --disable-static --enable-threads=posix --with-gnu-as --with-gnu-ld --with-stabs --with-fast-fixincludes --verbose

glibc options:
sedfile 's/object-suffixes += .og/#object-suffixes += .og/g' Makeconfig
mkdir Build ; cd Build
../configure --prefix=/usr --enable-add-ons=linuxthreads,crypt --disable-profile --disable-debug --disable-profile --with-elf --with-headers=/usr/src/linux/include --disable-static --enable-omitfp

i686-pc-linux-gnu glibc-2.1 linux-2.2

Note: gcc-2.8.1 with --enable-omitfp will fail later during glibc install process:
