Until we sort out a reasonable API and implementation for building up label strings, this will have to be sufficient. As outlined earlier this month, when we build up label names, part of the name is hidden in the backend, part in the caller. As a result there's no good way to get the length and size the array. sparc uses more characters than any other in-tree port and as a result it could (with sufficient local labels) do an out-of-range write into the name array when building a local label. This patch increases the buffer by one char which is sufficient to avoid the problem. Installing on the trunk.
