Hi, Running on -CURRENT _at_ Jan 20 with llvm 6.0.0, I have the following issue opening a core file with lldb: $ lldb /usr/local/bin/python2.7 -c /tmp/python2.7_90218_0.core (lldb) target create "/usr/local/bin/python2.7" --core "/tmp/python2.7_90218_0.core" Assertion failed: (template_counter >= 0), function ConsumeTemplateArgs, file /usr/src/contrib/llvm/tools/lldb/source/Plugins/Language/CPlusPlus/CPlusPlusNameParser.cpp, line 245. This nothing happens for a couple of minutes and then it dumps core. Interestingly though, it can open its own core: %> lldb /usr/bin/lldb -c /tmp/lldb_1129_0.core (lldb) target create "/usr/bin/lldb" --core "/tmp/lldb_1129_0.core" Core file '/tmp/lldb_1129_0.core' (x86_64) was loaded.

(lldb) Is that a known problem? Or maybe something wrong with my system? I don't use lldb very often, but I don't remember it crashing like that. Roman Bogorodskiy
