Hallo, the MS Standard C++ Libraries implementation in MSVCIRT directly accesses low level MSVCRT structures, like _pioinfo(), the pointer to an array of ioinfo structures. A google/search search brings up some information, e.g. (*1).
Some program in the Xilinx suite silently crashes when this _pioinfo() is accessed inside MSVCIRT with builtin msvcrt. How should we handle this case? Implement this array, in the same way as Microsoft did? Or can we construct a builtin MSVCIRT perhaps by using wrappers around some other Standard C++ Libraries implementation? At least a more visible way to crash when unimplemted structures are accessed would be fine. Comments welcome.
