Hi,

The needed data appears to be in the expected file, but
at a very unexpected location. So I am landing into
unknown territory and I need some time to investigate.

I do not need more data for now, you can allow the
file system to be updated again, and we will restart
from the beginning when I know more about the issue.

Regards

Jean-Pierre

This is the full file, and it is ok. I was trying to avoid
this, but being in unknown land, I now have to expand the
investigation zone, so the full file would have to be needed.

No worry, there is no user data there.

This failed because you used the option -c which prevents
from building an executable. I should have quoted the
compilation command :
gcc -o searchseq searchseq.c
