That's issue #2410. Quite a few crashes in SynEdit, all due to query threads in conjunction with non-threadsafe visual components.

Bugs due to third-party components? That's going to be fun...

I'm not reporting every crash I get with snapshots but the average figure is like a dozen per day unhappy

Well it's all one and the same problem: Query thread logs something to the sql log, which is a non-threadsafe TSynMemo and crashes. I thought I had everything synced with the main thread but obviously there is some code left which accesses the sql log from within the query thread, directly. Have to find it.
