Intel oneAPI ordinal base DLL issue.

MZ0xF — Mon, 08 Mar 2021 15:36:05 GMT

Hello all,

I am experiencing an issue with Intel C++ 2021 (2021.1.1) linker.

I have a script that modifies the PE's export list attribute in the DLL, after upgrading from 19.0 to oneAPI compiler I started to experience failures in this script.

After some investigation I noticed the ordinal base is maybe wrong, I am attaching a screenshot of the command "dumpbin -exports" on my DLL(without any modifications).

The ordinal base is "0" while the first exported function ordinal is actually "1".

Also, it lists 1426 while reporting 1427 I believe it also caused by the ordinal base being "0".

Please consult,

Thanks.

Hello,

Unfortunately, I can't attach my steps to reproduce because it's my company's product.

It happens only with ICX(Intel C++ 2021), I switched back to the classic one(19.2) and it works fine.

Thanks,

Max.

Hi Max,

The oneAPI toolkits have both the next generation compilers(ICX) and the classic compilers(ICC/ICL), is this issue specific to ICX or do you also see it with the later classic compiler that is part of oneAPI?

Also, could you please include a similar screen shot of dumpbin --exports for the correct case?

Hi Sravani,

Yes, the issue is only reproduced when I am using ICX.

After switching to the classic ICL(19.2) in the same oneAPI toolkit I am not encountering the issue.

I am attaching the screenshot you requested of dumpbin --exports with the correct case(using ICL).

Note that the number of functions different due to the development process.

Thanks,

Max.

Hi Max,

Is it possible to share the compiler and linker options used in case of ICL and ICX so I can try re-creating a similar test case at my end?
