Subject RE: [jira] Created: (STDCXX-48) [IRIX] std::wmemcpy() copies only the first character
Date Thu, 13 Oct 2005 22:53:26 GMT
The wmemcpy function was wrong so I changed it in cwchar.  It wasn't
incrementing the src pointer so only the first character of src was being
copied.

[IRIX] std::wmemcpy() copies only the first character
-----------------------------------------------------

         Key: STDCXX-48
         URL: http://issues.apache.org/jira/browse/STDCXX-48
     Project: STDCXX
        Type: Bug
  Components: 21. Strings  
    Versions: 4.1.2    
 Environment: IRIX 6.5
    Reporter: Martin Sebor
 Assigned to: Martin Sebor 
     Fix For: 4.1.3


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'\0' == dst [3]);
}
