Prevent using alloca and tempCString in same functions

Currently using both alloca and finalizers (==destructor call) in a function is
unsupported excepting Win32 (issue 3753). However compiler doesn't recognize
implicit destructor calls sometimes, and they're not called during stack
unwinding (issue 14708).

For the workaround, replace alloca call with malloc + scope(exit) free.
