AddStyle crashes

[ftrastour]

This bug was already signaled in ticket #2531; the summary of this ticket is good but not the content...

AddStyle? inconsistently uses CPLString().Printf() and causes a crash.

Here is a fix :

GBool OGRStyleTable::AddStyle?(const char *pszName, const char *pszStyleString) {

int nPos;

if (pszName && pszStyleString) {

if ((nPos = IsExist?(pszName)) != -1)

return FALSE;

m_papszStyleTable = CSLAddString(m_papszStyleTable,

CPLString().Printf("%s:%s",pszName,pszStyleString));

return TRUE;

} return FALSE;

}

There is another potential wrong usage of CPLString().Printf in OGRStyleTable::IsExist?.

A possible fix :

int OGRStyleTable::IsExist?(const char *pszName) {

int i;

if (pszName == NULL)

return -1;

const char *pszNewString = CPLSPrintf("%s:",pszName);

for (i=0;i<CSLCount(m_papszStyleTable);i++) {

if (strstr(m_papszStyleTable[i],pszNewString) != NULL)

return i;

} return -1;

}
