People say this a lot, you might be surprised how often it turns out that the input file *does* matter. Even if you think 'any file' will show the problem please always supply a file you *know* causes a problem, it will save time.

I see this too in gs 10.02.0, exactly same behavior on split, producing an output file with a blank page. It does not occur in 10.01.2 or 9*.

(In reply to Pascal Desjardins from comment #0) Thank you for the files. I will look into this as soon as I have a moment free.

Please don't 'me too' on bugs, either it is the same bug and will be dealt with when someone has a chance to look into it, or it is a different bug and should be reported separately. The simplest way to discover if this is the case is to wait until the original bug is fixed and test your own problem.

A 'thank you' for more samples would be much more polite. We devs... No words from me anymore. Let'e just sit and wait for a fix.
(In reply to Deny Dias from comment #8) > Right, right... things people hear when they think are helping. A 'thank > you' for more samples would be much more polite. I'm sorry you feel I was impolite, I didn't think I was, If I don't state our preferences on bug reporting, then how are people to know ? We don't want or need more samples, one is sufficient and the original reporter had already supplied 2 (you may notice I didn't complain about getting 2 files). (In reply to Pascal Desjardins from comment #0) I believe this commit will resolve the problem: 9b6fe6e1008f1b9b7fc3109b5f94db8d970fbcaa I've tested your original command line as well as odd, even, comma separated and - options. Thank you for the report.
Hi Ken, Last night we've updated Ghostscript to the 10.02.1 version and it seems this problem is occuring once again. Is it possible the fix you did was not included in the new version? Thanks for your help. Have a nice day

It is not included. Any patch version number (major.minr.patch) which is not 0 is a security release. Security releases *only* include code changes required to fix the security issue(s), they are otherwise identical with the previous release.
Hi Ken, Thanks for the quick reply, I didn't know about the version number. I will now. Sorry for the trouble. Have a nice day
