Dear All,

For the NEURON simulator project we have been using NVHPC 22.3 until now without issue. We are trying to use latest releases like 22.11 and 23.1 but seeing segfault in the following configurations:

  • -O2 or -O1 -g compiles fine
  • -O2 -g segfaults with following error:
$ /path.../Linux_x86_64/22.11/compilers/bin/nvc++ ivocvect.i -c -O2 -g

I have attached the preprocessed source file ivocvect.i from our project that you can use to reproduce the issue.

Please let me know if you need additional information.

Thank you!

P.S. I will upload here smaller reproducer if I get one via cvise/c-reduce

Hi Pramod,

Thanks for the report. I was able to reproduce the error with 23.1 but fortunately don’t see the error in our pre-release 23.3 version.

Though, in looking at the changes that went in when this started passing, they seem to me to be unrelated. Hence I went ahead and added a problem report, TPR #33056, asking engineering to ensure that the changes did indeed fix the issue as opposed to masking it.

Thanks for the quick update, Mat!

Do you know when 22.3 will be out?

Do you know when 22.3 will be out?

Not specifically, but most likely some time in March. Though occasionally things slip.
