Strange behavior of libstdc++ regression test

["Terry Guo" <terry dot guo at arm dot com>]

Hi,

I built a cross compiler for arm-none-eabi and ran regression test on QEMU
with command: "make -k check
RUNTESTFLAGS="--target_board=arm-none-eabi-qemu/-mthumb/-mcpu=cortex-m3"".

And then I end up with following strange errors on libstdc++:

A complete log file is attached. If the make target is check-gcc, everything
is fine. The Multilib is enabled and configured for different ARM targets. I
did some investigation and can't find any clue, could someone please help
me? Thanks.
