v8 bt skips some frames
Maybe there's a good reason for this, but notice we're skipping frames 1-4:
(lldb) v8 bt
* thread #1: tid = 13, 0x00007fda23874d44 libpthread.so.0`__GI___pthread_mutex_lock + 4, name = 'node', stop reason = signal SIGSEGV
* frame #0: 0x00007fda23874d44 libpthread.so.0`__GI___pthread_mutex_lock + 4
frame #5: 0x00007fda20ffe212 node`v8::internal::FunctionCallbackArguments::Call(void (*)(v8::FunctionCallbackInfo<v8::Value> const&)) + 290
[...]
They do show up with the normal bt:
(lldb) bt
* thread #1, name = 'node', stop reason = signal SIGSEGV
* frame #0: 0x00007fda23874d44 libpthread.so.0`__GI___pthread_mutex_lock + 4
frame #1: 0x00007fda20b0ed19 node
frame #2: 0x00007fda20ac5e39 node
frame #3: 0x00007fda20a9dd4b node
frame #4: 0x00007fda20a9c9f6 node
frame #5: 0x00007fda20ffe212 node`v8::internal::FunctionCallbackArguments::Call(void (*)(v8::FunctionCallbackInfo<v8::Value> const&)) + 290
[...]
Should "v8 bt" be skipping them?
