Yes. After make/error:
http://mahatma.bspu.unibel.by/download/transit/glibc-2.10.1-error.tar.bz2
(gentoo flavored, sorry)

New info: it happened on -O2 or -O3, and never on -Os".

Also I found how to get same on linux kernel x86_64: "make defconfig", but
remove "optimize for size" (CONFIG_CC_OPTIMIZE_FOR_SIZE) and add -ftracer. My
working config do not produce this. Next I attaching Makefile. You will need
only "make defconfig && make all" on x86_64 for vanilla 2.6.31 kernel (IMHO
simpler then glibc).
