please try the stock sim:libcxxtest first.

i did that, but when i use 'make distclean' it still going to have this problem. However, a while ago, I compared the configuration of cxxtest and nsh and found that need to turn on an optimization level at least -O1 in menuconfig, and then it work properly. thank you for your reply
