Execute Failed while SRC using <sstream> with armclang

Lately I'd obsessed over compiling STM32 project with ARMCLANG.

Here is Details:

Case 1. Used "#include <sstream>" in cpp file, complied successfully but execute failed, meanwhile I didn't use any function in <sstream>.

Case 2. Comment this code, project is fine.

Environment:

IDE: MDK 5.2.5

Compiler: armclang v6.9

SRC: c/c++ file.

Board: stm32f4 series(CPU Cortex-M4, Arch armv7-M).
