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.
