I realize this is frustrating, but it's not a simple situation since the the Python scripting version happens at random times; the Python crash is moderately reproducible (1 in 10 or so) but the hang is relatively rare... we never hit it during testing and it only happened after we put the new facility into production and we started to see hangs. > a) is there any chance you can compile LLDB from sources and use that > debugger to perform your automation? > The LLDB you would get that way is newer than the one you are trying > to use right now (and we fix bugs all the time, so you do want as new > as you can get) I could but it's just really tough. I could easily see if the "lldb -s" bug is fixed since that's 100% reproducible if you have the right (wrong?) kind of core file. We have a suite of OSX build servers (managed by Bamboo) so I'd have to deploy new LLDB to all of them, plus as a development team we'd have to agree to accept some hanging/unreliable OSX build server results for a while in order to try to track down this LLDB issue. That's a tough sell. > Also, > b) if the debugger hangs or crashes, it’s a bug and it should be fixed > - so, please file bugs for anything that does not work > And, again, if you are somewhat tracking our trunk, any and all bug > fixes, you get much more rapidly than staying on released Xcode > versions The problem is that it's Python that crashes, and no core is generated (that I can see). I'm not sure why not, or how to get more information about these crashes. Also this is using the /usr/bin/python (2.7.5) that comes with OSX. We have our own locally-built Python 2.7.8 and if I use THAT it dumps core every single time.

OK. I'll see if I can free up any time to dig into this more deeply. _______________________________________________ lldb-dev mailing list lldb-dev@cs.uiuc.edu http://lists.cs.uiuc.edu/mailman/listinfo/lldb-dev
