Comment (by pospeselr): As mentioned by cypherpunks, the issue here only occurs on the main thread which you can verify with a little spelunking through the glibc source. The relevant query APIs work expected on non-main threads since pthreads populates the required info in memory. Verifying a patch now on TreeHerder that fixes this issue by reading the __libc_stack_end symbol (glibc sets this void* to the first stack frame during program init). Solution suggested by mozilla's jld, and the folks in #jsapi (those paying attention at least) didn't seem offended at the idea of doing so for the main thread. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/20283#comment:18> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
