It is on dev. Also using dev biosig snapshot. It looks like a biosig
problem; I can reproduce it with hgid=c5447408b158.

I guess we can deal with this package later.

I wonder if that broke "biosig". I see:

I tried to reproduce the issue on Ubuntu 24.10 by configuring Octave with:

../configure --disable-java --disable-docs --enable-address-sanitizer-flags CPPFLAGS=-I/usr/include/hdf5/serial LDFLAGS=-L/usr/lib/$(dpkg-architecture -qDEB_HOST_MULTIARCH)/hdf5/serial CC=clang 'CXX=clang++ -std=gnu++17' 'CFLAGS=-ggdb3 -O0' 'CXXFLAGS=-ggdb3 -O0' 'FFLAGS=-ggdb3 -O0'

But the steps from comment #0 don't cause an issue for me:

$ LSAN_OPTIONS="leak_check_at_exit=0" ./run-octave -qf
octave:1> ls a
PKG_ADD
octave:2> addpath('a')
subdirs =
{
  [1,1] = junk1
  [1,2] = junk2
}

warning: called from
    a/PKG_ADD at line 2 column 1

octave:3>

These steps don't trigger any issue with the GCC ASAN for me either.

Am I missing something?

BTW, I noticed the problem when i was trying to load "biosig" package with ASAN compiled octave. PKG_ADD construct is from there.

Dmitri.

I think you're right that the problem is the loop over the elements of m_dir_info_list in load_path::set, but the problem is that the PKG_ADD file that causes the trouble results in a call to modify the m_dir_info_list object while we are inside that loop.

The PKG_ADD file was intended to allow commands like "autoload" to be executed when a new element is added to the load path, not to add more elements to the path.  I don't know how to easily fix this code to handle the possibility of recursively adding elements to the path.

Maybe it's also time to rethink the design decision that allows arbitrary code to be executed in a PKG_ADD file.

It still crashes:
