Hi. I'm using grep 2.25 in cygwin on a 17 MB log file. I happened to
notice that when I did "grep Migrate" on the file some lines were
missing. If however I did some other filtering first, i.e. "grep foo |
grep Migrate" (where foo would match those lines), they are included.
I cannot reproduce this issue with grep 2.5.4 on Linux.
I tried minimizing the log file by removing lines that I did not expect
in the output, but when removing lines before the expected line the
problem dissappeared, so somewhere in the first 17 MB (of my 50 MB file)
there is something triggering the bug.
Due to the nature of the logged data, I'm not willing to make the file
publically available in a bug report, but I'm willing to transfer it to
one of the maintainers, or by some other means help out in debugging.
Please suggest how to proceed.
