<h3 dir="auto">Describe the issue:</h3>
<p dir="auto">I am experiencing a NumPy crash in a rather complicated environment. I have a Fortran+MPI application, GEOS (<a href="https://github.com/geos-esm">https://github.com/geos-esm</a>) that calls a Python function at some point via a CFFI interface. My application crashes every time I try to 'import numpy' and the traceback looks like what is included in the 'Error message' section for each of the MPI ranks.</p>
<p dir="auto">Via test_crash_interface, FV_StateMod.F90 calls the Python function</p>
<p dir="auto">def import_numpy():<br>
import numpy as np<br>
print('imported numpy successfully')</p>
<p dir="auto">The application runs successfully if I do not import numpy. Also, I can import other modules, e.g. mpi4py, just fine.</p>
<p dir="auto">I tried to create a reproducer that simulates the GEOS infrastructure by using a simple Fortran driver, but in case of the reproducer, numpy is imported successfully. Also, I tried pybind11 instead of cffi as the Fortran-Python interface and I get the same crash.</p>
<p dir="auto">Please let me know if there is any other information I can provide.</p>

<p dir="auto">GCC    11.2.0<br>
Python 3.8.10<br>
NumPy  1.21.2 (same crash with 1.21.5 and 1.22.0)<br>

<p dir="auto">I have reproduced this error on 2 different systems - (1) Intel Cascade Lake node running SLES 12, SP5, and (2) AMD Rome node running CentOS 7.</p>
<h3 dir="auto">Describe the issue:</h3>
<p dir="auto">We recently embedded a python interpreter in a scientific Fortran code, and we are having problems with debugging floating point errors that happen inside our code. We typically do this by enabling all the floating point traps, but we can't get past the <code class="notranslate">import_array()</code> call during initialization due to a <code class="notranslate">SIGFPE</code>. This happens with multiple versions of NumPy, the latest we are using is 1.18.1, and it also happens with all versions of python, GNU compilers, and Intel compilers that we have tried.</p>
<p dir="auto">I vaguely recall seeing an email thread from a long time ago (that I cannot find again now) that links this to a for loop that continually multiplies a number until it overflows to define the limit for floating point numbers and I think that was related. Maybe somebody else can find it better than me.</p>
<p dir="auto">The two source files to reproduce it are below and can be compiled with:</p>

</code></pre></div>
<p dir="auto">In the event this isn't a bug or won't be fixed, we could use some advice on how to get around the floating point error problems in <code class="notranslate">import_array()</code> because it takes away a really critical tool for tracking down problems in our scientific core code.</p>
