Description LiRongQing 2013-09-26 05:35:12 UTC 
1. compile the slang test case by adding compile append in bb file

do_compile_append() {
cd src; make all; pwd; cd test; make sltest
}

2. put the sltest, strops.sl, and inc.sl from src/test to target


3. run test case, it failed.
./sltest strops.sl

4. simplify the test case as below:
4.1 the test script as below
root@qemu0:~# cat my1.sl 
printf("%s", sprintf("%c", ','));
4.2 if it work well, it should be print out ",", but it failed to print
root@qemu0:~# ./sltest my1.sl
root@qemu0:~# ,

5. I think it is toolchain bug, since I only need to add a print in source code,
this bug will disappear,
