[lldb-dev] occasional EXC_BREAKPOINT

[Greg Clayton]

We receive an EXC_BREAKPOINT and then we convert it to a breakpoint if we detect there is a breakpoint at that address. You should debug this function from StopInfoMachException.cpp:

StopInfoSP
StopInfoMachException::CreateStopReasonWithMachException 
(
    Thread &thread,
    uint32_t exc_type, 
    uint32_t exc_data_count,
    uint64_t exc_code,
    uint64_t exc_sub_code,
    uint64_t exc_sub_sub_code,
    bool pc_already_adjusted,
    bool adjust_pc_if_needed
)
