Greetings,
While investigating why a game (Kasparov's Chessmate) didn't work,
I think I found a bug in the implementation of imagehlp.dll in the
the MapAndLoad function located in dlls/imagehlp/access.c lines
165-167. The function looks like it tries to open an uninitialized
string szFileName instead of the passed file name "pszImageName".
I think there has been a bug filed already (Bug 6099 Alien Shooter
needs imagehlp.dll override) and I think this explains it.
Wine version 0.9.25
/***
* MapAndLoad (IMAGEHLP.@)
*/
BOOL WINAPI MapAndLoad(
LPSTR pszImageName, LPSTR pszDllPath, PLOADED_IMAGE pLoadedImage,
BOOL bDotDll, BOOL bReadOnly)
{
CHAR szFileName[MAX_PATH];
HANDLE hFile = NULL;
HANDLE hFileMapping = NULL;
HMODULE hModule = NULL;
PIMAGE_NT_HEADERS pNtHeader = NULL;
TRACE("(%s, %s, %p, %d, %d)\n", pszImageName, pszDllPath,
pLoadedImage,
bDotDll, bReadOnly);
/* PathCombine(&szFileName, pszDllPath, pszImageName); */
/* PathRenameExtension(&szFileName, bDotDll?:"dll":"exe"); */
/* FIXME: Check if the file already loaded (use
IMAGEHLP_pFirstLoadedImage) */
if(!(hFile = CreateFileA(
szFileName, GENERIC_READ, 1, /* FIXME: FILE_SHARE_READ not defined
*/
NULL, OPEN_EXISTING, 0, NULL)))
{
SetLastError(ERROR_FILE_NOT_FOUND);
goto Error;
}
Cheers,
Adam
