lldb stops on every call to dlopen
...but haven’t been able to reproduce.
Can your offer any suggestions for further debugging this? More supporting evidence follows.
Here is the message when the debugger stops:
Process 120004 stopped

lldb stops on every call to dlopen
...those every time the library is loaded (we need that to
load relevant debug info and set potential breakpoints). However, they
should generally not be surfaced to the user (unless you have the
stop-on-sharedlibrary-events setting set, which you don't).
The part that is suspicious to me is that __restore_rt shows up on the top
of the backtrace. This is a trampoline used to return from signal handlers,
and it would seem to indicate that you got some sort of a signal while
loading the libraries. I don't know why this would happen, but it could be
that this is confusing lldb's auto-resume logic....
