Yes, it solves my problem for now. Any magic to make it the default option ?
However, if the library grows up, I will fall one day or later in the
same issue.
Why MAXLINE is set to 102400 and not to a higher value ? (I guess
dynamic allocation is not possible)

I don't know what it does, but I get the same error than above:
actions too long ...

Volodya, I agree that this problem is not related with your patch,
which seems to work well for my project.
I think you can check in this change. Thanks again.
