[omniORB] omninames 4.1.0 for VC8 crashes when -errlog is specified

[John Stevenson-Hoare]

Hi Tahar,

 

Didn't experience this problem with 4.0.7 myself as we used the
pre-built version. Sounds a bit obvious but did you try debugging in to
the affected function to see why it crashes?

 

Cheers

John

Hi Guys,
I'm facing a kinda similar problem when compiling my application with
Visual Studio 2005 using omniORB4.0.7
As soon as the omniORB::Init() function is called, the program crashed,
windows returns an Acces violation error. 
Did you ever faced this kind of problem?

Thanks,

Cheers,

Tahar

	Sorry for the delay in replying to this. The problem is down to
a
	difference between Windows and Unix platforms. On Unix
platforms, the
	size parameter is the size of the buffer if one is provided,
which in
	this case there isn't. Windows takes it to be the size of the
buffer it
	should allocate.
	
	Windows doesn't support line buffering at all, so the code is
pointless
	there anyway. I've fixed it by #ifdefing it away on Windows. 
	
	Cheers,
	
	Duncan.
