<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>
