【OpenHarmony】【20210420】【轻内核子系统】集成测试：IO模块在相关接口的测试中会导致设备crash

该问题是怎么引起的？

IO模块在格式化相关接口（fwprintf、swprintf、wprintf、wscanf、Vwprintf、Vwscanf、Vfwprintf、Fwscanf、swprintf）的测试时，当测试用例函数参数中有“$”符号时，测试的时候会导致设备挂掉。

The format can contain either numbered argument specifications (that is, "%n$" and "*m$"), or unnumbered argument conversion specifications (that is, % and * ), but not both. The only exception to this is that %% can be mixed with the "%n$" form. The results of mixing numbered and unnumbered argument specifications in a format wide-character string are undefined. When numbered argument specifications are used, specifying the Nth argument requires that all the leading arguments, from the first to the (N-1)th, are specified in the format wide-character string.
