Hello Michael,
Reading this thread, I took a look at sal/rtl/source/strtmpl.cxx
969 static IMPL_RTL_STRINGDATA* IMPL_RTL_STRINGNAME( ImplAlloc )(
sal_Int32 nLen )
970 {
971 IMPL_RTL_STRINGDATA * pData
972 = (sal::static_int_cast< sal_uInt32 >(nLen)
973 <= ((SAL_MAX_UINT32 - sizeof (IMPL_RTL_STRINGDATA))
974 / sizeof (IMPL_RTL_STRCODE)))
975 ? (IMPL_RTL_STRINGDATA *) rtl_allocateMemory(
976 sizeof (IMPL_RTL_STRINGDATA) + nLen * sizeof
(IMPL_RTL_STRCODE))
977 : NULL;
978 if (pData != NULL) {
979 pData->refCount = 1;
980 pData->length = nLen;
981 pData->buffer[nLen] = 0;
982 }
983 return pData;
984 }
Since we cast "nLen" parameter in "sal_uInt32", could it help to add an
assert about nLen should be >= 0 ?
Of course, we don't expect a length to be negative but perhaps this function
is called with a negative value in very specific cases.
(advantage of the assert, it costs nothing in non debug)
