<br>
<tt>In any of the corefile, in frame 2 could you print </tt><br>
<tt> p *((struct qm_frag*)((char*)(p)-sizeof(struct qm_frag)))</tt><br>
<br>
<br>
<tt>Now, I see that the backtrace via libcurl & libcrypto may go via some error cleanup - see frame #7 and #8 - so , do you see any curl error prior to the crash (ideally from the same process) ?</tt><br>
<br>
<tt>If you can reproduce it easily, could you try without the async support, just as a PoC only.</tt><br>
