NetBSD emulation : application stack trace

[Mayuresh <mayuresh%acm.org@localhost>]

I am attempting to use Xilinx Vivado 2022.2 (Linux version) closed source
product on NetBSD 9.2 amd64 using Linux emulation.

Quite a few things are working now. However a certain use case is
consistently crashing with the following report:


    #
    # An unexpected error has occurred (11)

Wonder what course of investigation might be good for this:

- Incompatible libraries? But as the trace shows it's only libc.6 and
  libpthread.0 that are from the SuSE emulation. Rest is within the
  product's own libraries.

- Could it be an unimplemented Linux system call? In that case would
  NetBSD kernel give some indication?

- Could it be an emulation bug?
