Symbolic breakpoint crashes app. #182

Closed mediumbear closed 7 years ago

mediumbear commented 8 years ago

I've been enjoying Freddy, and have been using a symbolic breakpoint on JSON.Error. However my app started crashing in strange ways. I get an EXC_BREAKPOINT in my main thread in the runloop: callq 0x108f85468 ; symbol stub for: getpid. I'm using Freddy in another thread. If I look at that thread, it's always halted on a line decoding JSON. If I 'po' the code on this line the JSON decodes normally.
If I continue running, the main thread receives a SIGKILL. If I turn off the symbolic breakpoint, the app runs without error.

Has anyone ever experienced this problem? Thanks.

Can you provide details of what your breakpoint is doing? Additional stack frames from the main thread?

I have encountered this problem with breakpoints before in projects with no use of Freddy. I think it's an Xcode/LLDB/iOS quirk of some kind, but I've never been able to fully track it down.
