3.02 Effect Deletion When Duplicating Patterns

[Really Weird Person]

Full Version:
OpenMPT v1.17.03.02

Has the bug occured in previous versions? If yes, please specify version(s): (This option is optional, and doesn't need research. But in case you know...)


Description of the bug:
It would appear that if a string of patterns is duplicated, any effects that were in any of those patterns are lost. Note:  I have only used the pattern break so far, and only in the first channel, but I would imagine that it probably happens with any of them and in any channel.

How often does it happen?:
Always

How to reproduce (step by step description):
Step 1:  Start a song (The one I am working with has 94 patterns.)
Step 2:  Place an effect in any of them.
Step 3:  Begin duplication

I cannot reproduce such a thing. Afterall, it would be highly unrealistic that only effects would get lost when duplicating a pattern / several patterns, since duplicating by copying the complete memory of the old pattern to a new pattern.

Did you try to reboot windows?

Could be a one-time thing because windows is screwed up or something.

Tell me if it happens if you have rebooted windows and try it again.

Really, if patterns were not copied 1:1, then the RAM must be kinda broken, which would certainly not only affect modplug's pattern copy routine (which is actually just the bog-standard memcpy).

I tried it again, and it did not seem to happen. It was in a different channel though. Perhaps what happened is that I somehow inadvertantly deleted them (by deleting the channels perhaps) and therefore, the data was lost.

I'm closing this bug.

Feel free to post more evidence of this bug if you find any.

If there is a bug, we of course want to fix it.
