      I wonder if you could get gdb to read the debug symbols we provide in separate files (see the tor-browser-linux*debug.zip ones in https://dist.torproject.org/torbrowser/6.5.2/) to get better stack traces.

      My regular (production) tor browser is in dir /home/jb/Downloads/tor-browser_en-US/Browser/firefox I unzipped debug symbols file in dir: /home/jb/Downloads/Debug/Browser/

      Can you give me instructions how to set it up properly ? Then I can re-run the debugging session and capture whatever data you need to figure out what caused the dump.

      If I need debug symbols I usually create a .debug directory in tor-browser_en-US/Browser and copy the contents of Debug/Browser into that one. See: https://sourceware.org/gdb/onlinedocs/gdb/Separate-Debug-Files.html.

      Thanks. I ran TB with coredump and debug files. It dies as expected. If there is any post-run trace data (in addition to the above samples) of interest to you, let me know and I will capture it. I tried to trace with 'br main', couple of 'next', and 'continue', but this introduces delays and distorts order of events, signals and threads, and execution ran normally with TB window open, etc, and later exited normally. So, any trace data captured during such a run is useless.

      I e-mailed a link to the coredump file as requested.

      Btw, in unrelated matter, I see an error msg on TB startup: $ gdb ... (gdb) file Downloads/tor-browser_en-US/Browser/firefox (gdb) run ...

      Try to open a lot of pages and close them step by step, e10s is very crashy in such cases.

      That is a bit confusing but harmless. What happens is that Tor Browser checks for add-on updates but we prevent pinging Mozilla servers for Torbutton and Tor Launcher by setting the update url to data:text/plain,. The code is complaining then that cert validation failed as it expects an HTTPS URL and thus a certificate.

      I have been getting similar crashes as long as I can remember. They are seemingly random and it can be weeks without an occurrence (although they happen as a result of some action, e.g. loading a new page). This time I managed to capture and analyze the dump. This was the cause (version 7.5.4):

      It was a segmentation fault at PK11_ExitContextMonitor due to an invalid context pointing to freed memory (e5e5e5e5e5e5e5e5...) Before that, the C_DigestFinal in PK11_DigestFinal successfully returned CKR_OK, the buffer contained the correct result, and outLen was about to be set to 32...

      I will update this on the next crash to see if it occurs in the same place.

      Thanks a lot for that info. I wonder if what you are seeing is related to https://bugzilla.mozilla.org/show_bug.cgi?id=1444532.

      Thank you for a quick response. You are right, that definitely looks like it. It also activates only when a proxy is set which explains why my regular Firefox browsing seemed unaffected.

      So I guess this is not related to the original Arch Linux issue. But seeing this is getting fixed in ESR 60, I will leave it here. If I get another crash after the patch hits, I will let you know.

      I'll assume this was fixed with bug 1444532 in FF61.
