Issue with Audacity 3.7.1 on Ubuntu 24 - Macro paste error

Audacity 3 Help Forum GNU/Linux
1

Hello, my version of Audacity was recently upgraded and it broke a macro I have been running for some time. I have isolated it to this bit of code:

Select:End=“1800” Mode=“Set” Start=“0”
Cut:
NewStereoTrack:
Paste:

The error is:
“An internal error at libraries/lib-wave-track/WaveTrack.cpp line 1232”
The Paste operation is what generates the error.

OS:
cat /etc/os-release

I can confirm this bug. It is 100% repeatable for me with Audacity 3.7.3 on Linux.

The crash occurs when THROW_INCONSISTENCY_EXCEPTION is reached in this block of code:

void WaveTrack::ClearAndPaste(
   double t0,                      // Start of time to clear
   double t1,                      // End of time to clear
   const WaveTrack& src,           // What to paste
   bool preserve,                  // Whether to reinsert splits/cuts
   bool merge,                     // Whether to remove 'extra' splits
   const TimeWarper* effectWarper, // How does time change
   bool clearByTrimming)
{
   // Get a modifiable copy of `src` because it may come from another project
   // with different tempo, making boundary queries incorrect.
   const auto& tempo = GetProjectTempo(*this);
   if (!tempo.has_value())
      THROW_INCONSISTENCY_EXCEPTION;
   const auto copyHolder = src.DuplicateWithOtherTempo(*tempo);
   ClearAndPasteAtSameTempo(
      t0, t1, *copyHolder, preserve, merge, effectWarper, clearByTrimming);
}

I’d suggest that you log it as a new issue on Audacity’s GitHub (requires a free GitHub account) as the developers rarely visit this forum.

Thanks for the confirmation and deeper insight.
