There are two issues:
The unused global integer does not make it into the compiled object
file, so declare it static to correct this.
The hexdump output is line-wrapped, so the expected value will not
be matched when its four bytes are split across two lines. Use the
POSIX "-A n" option to disable printing input offsets and delete
all newline characters to output continuous hex values to grep.
