Sugar13:
when i type chinese char into the textbox, like this:

--- Code: ---#if (0xBABAD7D6 != '汉字')

--- End code ---

the cb will crash, and show a dialog with below message:

--- Quote ---Assertion failed!

Program: D:\ProgramC\CodeBlocks\codeblocks.exe
File: sdk\wxscintilla\src\scintilla\lexlib/CharacterSet.h
Line: 83

Expression: val >= 0

Where is the text box? How can I reproduce this crash? which version of C::B?

Sugar13:
textbox is where i input the source code, cb Build: Nov 25 2012, 09:32:38 - wx2.8.12 (Windows, unicode) - 32 bit, version is Release 12.11  rev 8629

OK, your C::B version is a bit old.
I don't have this kind of error in the recent nightly build version (Nightly builds), so I suggest you can do a upgrade. Also, maybe, you can try 13.12 RC (Release 12.11, RC1 has arrived).

Sugar13:
ok, svn build  rev 9455, this version is okey.

by the way, compiling the code makes a warning: multi-character character constant [-Wmultichar]

hao can i let the cb egnore this warning (hide this warning) ?
