<p>Eg in Seed_Magnetic_Field:</p>
<div class="codehilite"><pre><span></span><span> Avec[CCTK_GFINDEX4D(cctkGH,i,j,k,0)] = -(yL + 0.5*dY)*A_b*pow(MAX(Pressure_at_</span>
</pre></div>
<p>this causes test failures when compiled with <code>DEBUG=yes</code> or when enabling grid function eidex checking via other means.</p>
<p>Affected thorns seem to be:</p>
<ul>
<li>magnetizedTOV-Baikal (from Baikal)</li>
<li>GiRaFFE_tests_FFEBreak (from GiRaFFE)</li>
<li>GiRaFFE_tests_FastWave (from GiRaFFE)</li>
<li>GiRaFFE_tests_ThreeWave (from GiRaFFE)</li>
<li>magnetizedTOV (from IllinoisGRMHD)</li>
<li>magnetized_explosionTOV (from VolumeIntegrals_GRMHD)</li>
<li>magnetized_explosionTOV (from VolumeIntegrals_vacuum)</li>
<li>magnetized_explosionTOV (from particle_tracerET)</li>
</ul>
<p>Errors in the log file look like this:</p>
