Board index » cppbuilder » BCB2006: -Oi (Intrinsic optimization) fails with strcmp()

If I use -Oi (which is automatically activated by -O2) the strcmp()
function fails with
Error E2015 - Ambigiousity between
'cdecl __strcmp__(const char *,const char *)' and 'cdecl
std::__strcmp__(const char *,const char *
)' in function int mystrcmp(const char *str1, const char *str2)
int mystrcmp(const char *str1, const char *str2)
{
return (str1 && str2) ? strcmp(str1, str2) : (str1 ? 1 : (str2 ? -1 :
0));
}
But if I use -O1 or no optimization at all (debug mode) the file compiles
without errors.
I have already seen that in Debug mode (no optimization) the PCH creation
works but in Release mode (optimizations active) it always aborts PCH
creation with "Code in header" that is found in _str.h. And guess what
function: strcmp().
I'll see if I can create a reduces to the minimum testcase.

again don't count on it. Take a look at all the compiler bugs which were
reported and easily demonstratable for BCB5/BCB6 many years ago, and
were evidently, if one is to believe QC, never fixed for C++ Builder
2006, and you will get the idea about the importance Borland gives to
their own C++ compiler.
