Summary	0010274: Ardour crashes with SIGFPE arithmetic exception when opening minimal mixer session
Description	I'm on Fedora 44, latest upgrades. I build and run Ardour from latest git master (c583a57a2d). In this case, I'm using Ardour as a live mixer where I take in a number of virtual sources and a microphone and produce two separate output mixes (master + one through a foldback bus). The crash happened before I could set up the foldback. I had an unrelated random crash that I wanted to troubleshoot, so I purged all of my local Ardour configuration in an attempt to reproduce it. And when I tried to do a minimal setup (microphone bus with three ACE plugins + one or two buses who's inputs to virtual sinks) I instead got the crash I'm reporting here. The hardware I'm using for the microphone is a Yamaha AG06.
Steps To Reproduce	Unfortunately I've tried to redo the below, but can't reproduce the issue myself. But I still have the Mixer session (that I've attached as Mixer.zip) which causes the crash when I open it. This is just a step-by-step of what I remember doing: * Purge local ardour configuration (move / remove ~/.config/ardour9). * Make a virtual source, a suggestion is to use`pactl load-module module-null-sink media.class=Audio/Sink sink_name=Web channel_map=stereo` but any virtual sink made by pipewire should do it. * Connect some high quantum audio source to it, like a browser with qpwgraph and play audio through it. * Create empty Ardour Session, go through the setup wizard, set UI scale to 100%. * Connect it to jack/pipewire. * Go to the Mix view and add a stereo bus for the virtual source. * Route the virtual sink to its inputs and output it by default to master. Here for me I remember the left channel was always peaking on the meter for some reason. * Add a bus for the microphone and add pre-fader filters (ACE Expander, ACE Compressor, ACE Amplifier). This was also peaking. * Exit the session. * Try and open the session again. * This is where it crashes for me.
Additional Information	I ran it with `ardour --gdb`: ``` Thread 1 "ArdourGUI" received signal SIGFPE, Arithmetic exception. 0x00000000008a70ae in Editor::set_timecode_ruler_scale (this=0x2d10160, lower=0, upper=5195776) at ../gtk2_ardour/editor_rulers.cc:870 870 const samplecnt_t hours_in_range = range / (60 * 60 * fr); (gdb) p fr $1 = -9223372036854775808 ``` The culprit seems to be that `_session->sample_rate()` reports said value on my system / configuration for some reason. I've attached the full backtrace as ardour-bt.log
Tags	No tags attached.

udoprog 2026-04-09 16:24 reporter ~0030190	So I was trying to redo my setup. This time I had created three stereo buses, no microphone bus. I was assigning them prefader to a new foldback bus. When I assigned them, panning for all the audio buses I was assigning to the foldback bus went fully to the left. And when I saved and tried to open the session again the same crash occurred.

udoprog 2026-04-09 19:31 reporter ~0030193	After debugging, the root cause for all sessions I've examined seems to be that somehow this configuration values gets set: <Option name="video-pullup" value="inf"/> When it's used in this calculation in `Session::sync_time_vars ()`: _current_sample_rate = (samplecnt_t) round (_base_sample_rate * (1.0 + (config.get_video_pullup()/100.0))); It results in an inf being casted to samplecnt_t, which when multiplied by an even number like 60 * 60 results in a 0 for the denominator, causing the crash.

udoprog 2026-04-10 00:45 reporter ~0030194	So broadly speaking what I've noticed is that something has managed to set most if not all the floating point variables in my session to `inf`. I have another bigger session where this has happened too, and it causes similar crashes in multiple other locations. I think that means that there's two separate issues: The first problem is my Ardour session being corrupted filling most (if not all floats) with `inf`. This seems like the more critical issue, since even if I can convince Ardour to load the session later it has been corrupted and cannot be recovered. At the moment I have no idea why this happened to begin with. The second issue is Ardour crashing on startup when loading sessions that contain invalid configuration. The typical crash I've noticed boils down to an inf being converted into a 0 by first casting it into an integer and then multiplying that with something. Calls to `double_npm_to_scpn` are clear examples of this. And anything else that uses XMLNode::get_property and loads the result without checking it is suspect. This should probably be a separate ticket if it doesn't already exist.
