Re: g_locale_to_utf8

[Viraj Chatterjee <vchatter adobe com>]

Who is losing which pointer?

g_locale_to_utf8 returns the UTF-8 string in an allocated buffer. It's the 
API user's responsibility to do the clean-up.
s is receiving such a buffer from g_locale_to_utf8 and hence must be freed, 
after you're done with using s, in this example, the only use is the 
gprintf.

If the intention is to use 's' further in the code, then obviously it 
shouldn't be freed now, but should be freed sometime later, when you're done 
with using it.

Look at the sources, there is a g_malloc being done for the string to 
return, and it isn't being freed anywhere.
