<p>Hi,</p>
<p><br>
</p>
<p>I keep getting the following error <b>after </b>I have generated llvm IR ( using a Module->print(errs(),nullptr) ) -<br>
<br>
<b>"<span>pure virtual method called terminate called without an active exception."</span></b></p>
<p><br>
</p>
<p><br>
</p>
<p>On the last line of the program , after everything has been executed , I get this error. <br>
Can anyone explain this ?</p>
<p><br>
</p>
<p>Following is my LLVM IR - ( Kindly do not pay attention to semantics as it is for a personal project)<br>
When compiled using llvm-as and then lli , it works as expected.<br>
<br>
<br>
<br>
