The\n%s conversion skips leading whitespace, while strcspn() does not.\n\nIf a client debug entry starts with a space, the allocation can be sized\nfor an empty keyword while sscanf() copies the following non-empty token.\nThis can write past the end of the allocated keyword buffer.\n\nSkip leading spaces before computing the keyword length so the allocation\nmatches the string parsed by
