[Tuxpaint-devel] Locale detection problem on 64bit version for windows.

[TOYAMA Shin-i. <sh...@wm...>]

Hi developpers,

At first, please take note that the problem is that 64bit
executable for windows crash when it start unless specific locale 
is set by config/command line option/environment variable.

I found that the crash occurs in mysetenv() in i18n.c when 
strlen(value) is called.

The address of the string 'value' is passed from 'loc' which is
set by calling _nl_locale_name() in set_current_language().

I checked the return value 'loc' from _nl_locale_name() by;

  printf("%s", loc);

It results "ja_JP" on 32bit executable but, crash occurs on 64bit 
version.

I am quite at a loss how I should do so far.

Anyway, I think it would be better to stop releasing the 64bit
version until this will be fixed.

Thanks.
