[MSVC 7] operator new doesn't throw on failure
----------------------------------------------
Key: STDCXX-79
URL: http://issues.apache.org/jira/browse/STDCXX-79
Project: STDCXX
Type: Bug
Components: External
Versions: 4.1.2
Environment: MSVC 7.0, 7.1
Reporter: Martin Sebor
Priority: Critical
The implementation of operaror new in the MSVC 7 runtime library (but not the
one in the C++ Standard Library, msvcprtd), fails to throw an exception on
failure and instead returns 0. This works correctly in MSVC 8.
Here's a reference to the MSVC 7 documentation of their libraries:

$ cat t.cpp && cl /EHsc /MDd t.cpp /c && link /NODEFAULTLIB:msvcprtd t.obj &&
./t
#include <cassert>
#include <new>
#include <crtdbg.h>
int main ()
{
_CrtSetReportMode (_CRT_WARN, _CRTDBG_MODE_DEBUG);
_CrtSetReportMode (_CRT_ERROR, _CRTDBG_MODE_DEBUG);
_CrtSetReportMode (_CRT_ASSERT, _CRTDBG_MODE_DEBUG);
int success = 0;
try {
operator new ((unsigned long)-1024);
}
catch (std::bad_alloc&) { success = 1; }
catch (...) { }
assert (success);
}
