Should be fixed now, please check the new Version 1.0.7.2

Additionally the Airport Name can take Unicode characters, now.

Sorry, the problem persists obviously. From the dunp I can see that the parser is crashing ... but the cause for the Crash is in timline before and the dump doesn't contain the data being parsed, so I still can't reproduce the crash. I tried to generate the input myself by UTF-8 encoding the name "ganadist의 iPad" and parsing it but it didn't Crash. So it would be great if you would record a trace to file and provide this file for download once more.

Thank you very much

Thank you again for your kind reply.
But how can I record a trace file?

Shairport4w has a log to file option. But I guess its capabilities aren't sufficient for the need to log these special characters. I will provide an improved Version next weekend

Okay. I'll wait a next version. :D
Thank you.

I've install the shiny newest visual studio 2013 (trial!) and tried to debug. :)

Then I found there is something wrong in strlwr_s().

I tried to use own strlwr replacement (using stl), crash disappeared.

I guess there is a problem that handle non-latin character on strlwr_s().

utils.h.patch

On http://msdn.microsoft.com/en-us/library/y889wzfw.aspx, strlwr can handle string by "current locale", but in my case, input string is always utf-8, not locale.

You are right. The Parser utilized the strlwr version from the checked namespace, which threw an exception in case of an error - unnecessary. I uploaded a new version of Shairport4w which hopefully will work finally.

Thank you
