[erlang-questions] Do I need sasl to log crashes in the gen_server init function ?

[Ahmed Omar]

Another way to see the actual exception in shell , is to start your
gen_server directly from there.
But in production, you will probably start it the proper way under a
supervision tree, and using the application controller so you better have
sasl running.

2> application:start(myapp).
{error,{shutdown,{myapp_app,start,[normal,[]]}}}
3>
=INFO REPORT==== 16-Dec-2010::14:21:55 ===
    application: myapp
    exited: {shutdown,{myapp_app,start,[normal,[]]}}
    type: temporary

3> test:start_link().
** exception exit: {badmatch,false}
     in function  test:init/1
     in call from gen_server:init_it/6
     in call from proc_lib:init_p_do_apply/3
