Occurs while compiling glibc-2.7-20080428 with gcc-4.4-20080411 while building
the shared object for malloc.c.  gcc-4.2.3 works with the identical setup.

$ gcc-4.4-20080411 -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc-4.4-20080411/configure --prefix=/system/devel
--program-suffix=-4.4-20080411 --enable-shared --enable-static
--with-system-zlib --enable-languages=c,c++ --enable-decimal-float --enable-tls
Thread model: posix
gcc version 4.4.0 20080411 (experimental) (GCC)

../glibc-2.7-20080428/configure --prefix=/system/libs --with-tls
--enable-shared --enable-static

$CC = /system/devel/bin/gcc-4.4-20080411 -march=pentium
-mno-tls-direct-seg-refs
$CFLAGS = -O2

Compiler output:
/system/devel/bin/gcc-4.4-20080411 -march=pentium -mno-tls-direct-seg-refs
