Description

The program below aborts at runtime when compiled with SGI MIPSpro and run on SGI IRIX 6.5. Note that IRIX doesn't define wmemcpy (the macros _RWSTD_MO_WMEMCPY and _RWSTD_MO_WMEMCPY_IN_LIBC are both defined) so the called function must be ours.

$ cat t.cpp && nice gmake t -r && LD_LIBRARY_PATH=../lib ./t
#include <cassert>
#include <cwchar>

int main ()
{
wchar_t dst [4] =

{ 0, 1, 2, 3 }

;
std::wmemcpy (dst, L"abc", 3);

assert (L'a' == dst [0]);
assert (L'b' == dst [1]);
assert (L'c' == dst [2]);
assert (L'\3' == dst [3]);
}
