Summary0009887: Floating Point Exception on startup (race condition)
DescriptionThis appears to be a race condition. When Ardour loads, there is potentially a memory warning:

```
WARNING: Your system has a limit for maximum amount of locked memory. This might cause Ardour to run out of memory before your system runs out of memory.
```

If you dismiss it fast enough, or click the box to disable it (which adds `<no-memory-warning/>` to instant.xml in the config directory), then everything starts up fine. But if you wait a few seconds (e.g., enough time to read the message), Ardour fails with

```
Floating point exception (core dumped)
```
Steps To Reproduce1. Start Ardour somehow (.desktop, console, etc.)
2. have ulimit with a limit for maximum amount of locked memory to trigger the warning
3. allow a moment long enough to read the warning
4. Ardour shuts down abruptly (observe exception in console log)

Additional InformationConsole log from start

Dismissing the ulimit message is a workaround. Seems to allow some initialization to happen in the correct order.

I cannot reproduce this here.
Does this also happen with the official binary, and if so can you get a backtrace of the crash?
https://ardour.org/debugging_ardour

Thanks in advance.

This was from a precompiled binary I downloaded.

The crash is deterministic for me (i.e., not intermittent). If I find more time to go back and mess with it I'll make another note here. I'm just setting up a new system and the issue is resolved for me.

The problem reproduces for me on NixOS, which builds Ardour from source. I have noticed that it reproduces with a user interface scale of 200% but it doesn't with a scale of 150% or 100%.

Ardour8.8.0 (built using 8.8 and GCC version 13.3.0)
Linux chulak 6.6.59 0000001-NixOS SMP PREEMPT_DYNAMIC Fri Nov 1 00:58:34 UTC 2024 x86_64 GNU/Linux

I've attached a backtrace from when it did crash. The crashing thread is thread 1.
