N_CATCH
=======

 - `.stabn': N_CATCH
     GNU C++ `catch' clause

     GNU C++ `catch' clause.  The value is its address.  The desc field
     is nonzero if this entry is immediately followed by a `CAUGHT' stab
     saying what exception was caught.  Multiple `CAUGHT' stabs means
     that multiple exceptions can be caught here.  If desc is 0, it
     means all exceptions are caught here.
