Description: Ardour 6.9.0 crashes on exporting audio
Setting:
1. So far it happens when exporting the project to an audio file--flac format in these cases.
2. I create a mono project from a template with all LV2 plugins (EQ, Gate, FastLookahead Limiter, Expander, Compressor)
3. I drag and drop one file into the template, track, reduce the whole region gain by 1 or 2dB, then export it to flack.
4. Usually I do NOT do any editing of the region except the gain. If I do more editing, it seems more likely to crash.

Frequency: Not every time and not at any particular point in the export, but it is more likely to happen after creating and exporting several different projects, one after the other.
