bug report: C::B crash when I remove the target from a cbp
ollydbg:
Steps to reproduce this crash:
1, open a cbp project which has some targets
2, open the cbp property dialog, and delete some targets.
3, press the OK button of the dialog
4, C::B crash
I'm using the latest rev 12977
The crash call-stack looks like below:

I also upload the gif file of the operation.
Thanks.
AndrewCot:
I just loaded a copy of my CodeBlocks_Windows.cbp and deleted a few targets and did not get the crash. I closed C::B and reloaded the cbp file and deleted some more targets and it did not crash. I am using SVN 12979 (same code as 129879 , but with updated SVG files) built with MSYS2 Mingw64 GCC 12.2 (last updated about 6 hrs ago).
I then tried with the nightly 12969 and did not get a crash. I tried with both the latest MSYS2 MinGW64 libstdc++-6.dll and the nightly official DLL from 2018 and still did not get a crash.
Can you try the nightly 12969and see if it crashes?
ollydbg:
Hi, AndrewCot, thanks for the test. I will try the official nightly build.
My guess is that I have some macro(global compiler variable) in the cbp, for example:
--- Code: ---<Add option="`$(#WX_CONFIG) --cflags`" />
--- End code ---
Do you have such kinds of macros in the cbp?
AndrewCot:
I have a bunch of macros, but this one does not have the wx-config macro. Attached is the original project file before I did any testing.
I just tested with my old (as in I have not touched it in a month ) MSSY2 proejct file that uses wx-config macro and it does not crash with 12979. I have also attached it.
Pecan:
I see that just before the crash ConfigManager::GetUserDataFolder() was called.
But I don't see (in the crash report) from where it was called.
It can only be called from
--- Code: ---void ConfigManager::InitPaths()
{
ConfigManager::config_folder = ConfigManager::GetUserDataFolder();
--- End code ---
or
--- Code: ---wxString CfgMgrBldr::FindConfigFile(const wxString& filename)
{
wxString u(ConfigManager::GetUserDataFolder() + wxFILE_SEP_PATH + filename);
--- End code ---
GetUserDataFolder() does some weird things.
--- Code: ---inline wxString ConfigManager::GetUserDataFolder()
{
if (has_alternate_user_data_path)
return alternate_user_data_path;
#ifdef __WINDOWS__
TCHAR buffer[MAX_PATH];
if (!ConfigManager::has_alternate_user_data_path && ::GetEnvironmentVariable(_T("APPDATA"), buffer, MAX_PATH))
return wxString::Format(_T("%s\\CodeBlocks"), buffer);
else
return wxStandardPathsBase::Get().GetUserDataDir();
#else
#ifdef __linux__
gchar *filename = g_build_filename(g_get_user_config_dir(), "codeblocks", nullptr);
wxString result=wxString::FromUTF8(filename);
g_free(filename);
return result;
#else
return wxStandardPathsBase::Get().GetUserDataDir();
#endif // __linux__
#endif // __WINDOWS__
}
--- End code ---
It calls:
--- Code: ---if (!ConfigManager::has_alternate_user_data_path && ::GetEnvironmentVariable(_T("APPDATA"), buffer, MAX_PATH))
--- End code ---
Where GetEnvironmentVariable() is declared as (in my system)
--- Code: --- __MINGW_NAME_AW(GetEnvironmentVariable)
WINBASEAPI DWORD WINAPI GetEnvironmentVariableA (LPCSTR lpName, LPSTR lpBuffer, DWORD nSize);
WINBASEAPI DWORD WINAPI GetEnvironmentVariableW (LPCWSTR lpName, LPWSTR lpBuffer, DWORD nSize);
#define GetEnvironmentVariable
--- End code ---
in msys64_13.0.1\mingw64\include\processenv.h
where it crashed in libstdc++-6.dll;
What in the world is it doing.
Or might there be some mixed up system dll's in your system. (Just trying a guess)
Maybe try a full build and see if the problem goes away.
