If using pthreads, then gdb already has support for that (I frequently debug threads issues for CM3 using the regular gdb without any problems). If using SIGVTALRM threads then I would suggest that users will need to be familiar with the thread scheduling points that it uses (triggered by SIGVTALRM, and implemented by Thread.Transfer). Since there is no way for m3gdb to "switch" contexts for SIGVTALRM threads then it really might as well be agnostic about threads generally. In summary, there should not be need for *special* support for threads in m3gdb.</div><br><div> <span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0);
