Description
Looking at seq oss fuzz coverage, I noticed that it wasn't producing much.
Writing a fuzz on seq parse number, i noticed that:
cargo run seq 4e4000003 4e4000003
is running forever
while GNU is doing:
$ LANG=C /usr/bin/seq 4e4000003 4e4000003
/usr/bin/seq: invalid floating point argument: '4e4000003'

Research direction
Start by reproducing the reported cargo run seq 4e4000003 4e4000003 command and tracing seq's number parsing and iteration logic. Done means this input terminates with an invalid floating-point argument error rather than looping indefinitely, consistent with GNU seq.
