Ticket #108 App crashes when pressing F9 / compile+run

oBFusCATed:
Can someone try to reproduce the crash from ticket #108? https://sourceforge.net/p/codeblocks/tickets/108/
I've not tried it on linux, but I suppose it is windows only.

I has problems to access to SF (SF was blocked by my country from time to time >:( )
So, I wrote here, I just see the backtrack from GDB

[debug]>>>>>>cb_gdb:

--- End code ---

It is related to dependlib in the line:

--- Code: ---void path_split(const char *path, PATHSPLIT *f)
{
const char *p = path;
#ifdef DEPSLIB_WINDOWS
// support UNC filename in windows: ignore leading slashes
while ((*p == '/') || (*p == '\\')) //******************* crash here***********************
++p;
#endif
PATHPART *part;

f->count = 1;
f->part[0].ptr = path;

--- End code ---
Here, p is 0.

ollydbg:
It looks like the special folder "testabcă"

--- Code: ---source_file_absolute_native = L"D:\\temp\\testabc\003\001\\acb\\main.cpp"
--- End code ---
and then:

--- Code: ---bool DirectCommands::IsObjectOutdated(ProjectBuildTarget* target, const pfDetails& pfd, wxString* errorStr) const
{
// If the source file does not exist, then do not compile.
time_t timeSrc;
depsTimeStamp(pfd.source_file_absolute_native.mb_str(), &timeSrc);
--- End code ---

But source_file_absolute_native.mb_str() failed and return a 0.

ollydbg:

--- Code: --- wxString msg = wxT("abcă");
const char *pppp = msg.mb_str();

--- End code ---
On WinXP
Under wx2.8.12, I get the pppp value is 0.
Under wx3.0, I get pppp is not zero, but *pppp is 0.

BlueHazzard:
Still a problem with wx3.0.2 on win 7 64bit

interesting that a conversion from "internal" utf16 to "external" utf16 fails, but

--- Code: ---wxString msg = wxT("abcă");
const char *pppp = msg.ToUTF8();
--- End code ---
is working like a charm....

Anyway: codeblocks should not crash if a conversation fails, so there should be a null check, because wxString::mb_str() can fail:
http://docs.wxwidgets.org/trunk/classwx_string.html

--- Quote ---String in the current locale encoding implicitly or using c_str() or mb_str() methods. This is a potentially destructive operation as an empty string is returned if the conversion fails.
