[Octave-bug-tracker] [bug #66477] ASAN error with path(_) manipulations

[Markus Mützel]

Update of bug #66477 (group octave):

                  Status:                    None => Need Info

Follow-up Comment #10:

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: addpath:
/home/osboxes/Documents/Repositories/Octave/octave-2/.build-asan-clang/a/junk2:
No such file or directory
warning: called from
    a/PKG_ADD at line 2 column 1

warning: addpath:
/home/osboxes/Documents/Repositories/Octave/octave-2/.build-asan-clang/a/junk1:
No such file or directory
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?
