> ----------------------------------------------
>
> Key: STDCXX-79
> URL: https://issues.apache.org/jira/browse/STDCXX-79
> Project: C++ Standard Library
> Issue Type: Bug
> Components: External
> Affects Versions: 4.1.2
> Environment: MSVC 7.0, 7.1
> Reporter: Martin Sebor
> Assignee: Farid Zaripov
> 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:
> http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclib/html/_crt_c_run.2d.time_libraries.asp
> $ 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);
> }
