<div>Hi Itary, I identified the cause of the problem with your app. The compiler works correctly, but one of the tools, clang-offload-bundler, produces a lot of junk in the bundled object files and it breaks linking. I'm working on the fix.<br>
<br>

<div dir="ltr">Hi,
<div>I am revisiting this possible compiler bug in Clang 8.0.0.</div>
<div><br>
</div>
<div>In the source code I am developing, there's a global static variable, nest::sli_neuron::recordablesMap_ put in the BSS section and it is expected to be fully initialized by the time nest::sli_neuron::sli_neuron() gets called, however in a gdb session:</div>
<div><br>
</div>
<div>(gdb) p nest::sli_neuron::recordablesMap_</div>
Python Exception <type 'exceptions.AttributeError'> 'gdb.Type' object has no attribute 'name':<br>
$1 = {<std::map<Name, double (nest::sli_neuron::*)() const, std::less<Name>, std::allocator<std::pair<Name const, double (nest::sli_neuron::*)() const> > >> = std::map with 0 elements, _vptr$RecordablesMap = 0x0}
<div><br>
</div>
<div>this doesn't happen when -fopenmp-targets is _not_ used, is it not trivial to come up a reproducer, thus I am sending a work-in-progress report hoping someone will shed some light on this.</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Itaru.</div>
