VC++2012: Fatal Error C1001 since Release Candidate

Question

Hi,

While recompiling a DLL which makes heavy use of PPL and C++ AMP, a fatal error C1001 now triggers in the VC++ 2012 Release Candidate:

1>S:\SRC_vs11\abc\def.cpp : fatal error C1001: Une erreur interne s'est produite dans le compilateur.

(in Debug or Release configurations, Win32 or x64 targets)

What kind of information should I send for diagnosis ?

Answer 1

Hi Arnaud,

Thanks for reporting this. Is it possible for you to reduce the code to get a small project that can be shared with us and can show the same problem? If that's the case, it would be a lot easier for us to investigate.  Otherwise, this support article http://support.microsoft.com/kb/974229, shows how to create compiler/linker repro that could help the investigation. Any way works for you, please drop me an email at (weirong.zhu  @ the company you know . com, :)),  I will assist you offline, and see if we can gather enough information for identifying the problem.

Thanks,

Weirong

In addition to Weirong's response, also see this article about compiler/linker repros:

Answer 3

Thanks Weirong and Daniel,

I've just sent to you the minimal project...

Best regards, Arnaud.

Answer 4

Got it! Thanks very much Arnaud! We appreciate the repro and will investigate!

Update: our engineer has identified the bug and will fix it for the final product. Thanks again for reporting it!

Answer 5

This compiler error is gone with Visual Studio 2012 RTM (from MSDN). Thanks to all.
