Summary	0008908: Crashes when exporting to audio file.
Description	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 flac 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.
Steps To Reproduce	I cannot directly reproduce the crash, but it tends to happen only while exporting to audio.

Ardour 6.9 - crash on file export (LWP 71654 gdb backtrace).txt (76,311 bytes)

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.

Ardour 6.9 - crash on file export (LWP 71654 gdb backtrace).txt (76,311 bytes)

Ardour 6.9 - crash on file export (LWP 97375 gdb backtrace).txt (67,995 bytes)

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.
