## See output-limit.yaml. While estimating the size of the last byte of .crel.text
## (a SLEB128), checkLimit thinks 10 byte headroom is needed while only 1 is used.
## The file end is 1 byte away from the end of .crel.text (one-byte .strtab).
## Therefore, the --max-size= value has to be at least 10-1-1 larger than the
## actual file size.
