[sc-dev] more details about tcp crashes

[Sciss <contact@xxxxxxxx>]

hi,

today i saw one very rare thing with the bug described before  
(SuperCollider.app crashing when TCP connections are closed) : in  
this case, the app didn't crash but sclang posted an error message in  
the post win:


ERROR: Message 'prConnectionClosed' not understood.
RECEIVER:
Instance of 8l {    (1776DEF0, gc=6B, fmt=4C, flg=61, set=65)
  indexed slots [4]
unknown obj_format 4C
}
ARGS:
CALL STACK:
	DoesNotUnderstandError:reportError   16842DE0
		arg this = <instance of DoesNotUnderstandError>
	Nil:handleError   16842D20
		arg this = nil
		arg error = <instance of DoesNotUnderstandError>
	Object:throw   16842CC0
		arg this = <instance of DoesNotUnderstandError>
	Object:doesNotUnderstand   16842C60
		arg this = <instance of 8l>
		arg selector = 'prConnectionClosed'
		arg args = [*0]

(that's all, the stack trace looks truncated, i don't know)


for convenience, here's a again the info about the "normal crashing":
