The bug is in the buffer_append_space() function, which operates on Buffer structs; these structs have a buffer initialized through malloc(), so StackGuard is unlikely to have any impact on any potential exploits. The vulnerability comes when the fatal() function calls cleanup handlers that rely on potentially corrupted data. This patch corrects buffer_append_space() to maintain consistent state.
