Description of problem:
Running emacs + lsp on zephyr rtos code project.
Adding parameters to a C macro and I mistyped: MACRO_NAME(a b, c) and mistyped MACRO_NAME refer to below
Missed the comma after the first parameter.
Abrt reported clangd faulted.
Note, I'm using zephyr Device Tree macros making the parsing more complicated.
static const struct espi_mec5_host_index_config espi_mec5_vw_reg_map[] = {
    DT_FOREACH_CHILD_STATUS_OKAY(DT_PATH(mchp_mec5_espi_vw_map), MEC5_DT_VW_REG_MAP)
};
#define MEC5_DT_VW_REG_MAP(n) \
{
   ..., \
  MEC5_DT_CTVW_IRQ_SEL(n), \
},
#define MEC5_DT_CWVW_IRQ_SEL(n) \
  COND_CODE_1(DT_NODE_HAS_PROP(n, vw_interrupt_sels), \
                                    (MEC5_DT_CTVW_ISEL(n)), (MEC5_DT_CTVW_NO_ISEL))
#define MEC5_DT_CTVW_NO_ISEL(n) \
    .irq_sel = { \
      DT_FOREACH_PROP_ELEM(n, vw_source_names, MEC5_DT_CTVW_ISEL_BY_NAME), \
    }
#define MEC5_CT_CTVW_ISEL_BY_NAME(n prop, idx)

With two levels of DT_FOREACH_... and incorrect names by me, clangd got very upset.
