* configure outputs and VC input for deckN
* load track <--
* enable passthrough
* load another song
* deck overview shows "Analyzing..." string then GUI freezes instantly
* GUI updates every 30 seconds or so, one Mixxx thread uses 100% of CPU
* click passthrough button
* on next GUI update it 'unfreezes'

I could reproduce this with I/O both on integrated card of TerminalMix 2/4, as well as with loopback device and no controller attached.

reproducible with
2.3 352f75428b --> crashes with std::bad_alloc, see backtrace
main c126267767 --> freezes until passtrhough is disabled
