Description John Eckersberg 2015-12-15 17:51:58 UTC 
+++ This bug was initially created as a clone of Bug #1291822 +++

Erlang aborts in dist_port_command with ERTS_ABORT_EXIT:

    if (size > (Uint) INT_MAX)
	erl_exit(ERTS_ABORT_EXIT,
		 "Absurdly large distribution output data buffer "
		 "(%beu bytes) passed.\n",
		 size);

However, ERTS_ABORT_EXIT inhibits erlang crash dump generation.  It would be better to exit with ERTS_DUMP_EXIT so a crash dump is generated, in order to help debug crashes from large messages.
