[Octave-bug-tracker] [bug #63388] Octave may crash with uitable containing true/false data

[Arun Giridhar]

Follow-up Comment #17, bug #63388 (project octave):

I built Octave with these settings:

export CC="gcc"
export CXX="g++"
export F77="gfortran"
export CFLAGS="-pipe -march=native -O0 -ggdb3 -fsanitize=thread,undefined"
export CXXFLAGS="$CFLAGS"
export FFLAGS="$CFLAGS"

../configure --enable-64 --enable-openmp --disable-java --disable-docs
--disable-lib-visibility-flags


(The disable-lib-visibility was required with "-fsanitize=undefined" otherwise
it kept giving undefined symbol linker errors).

Running the two tests from the OP, there are several race conditions that show
up. Attached logs if anyone finds them useful.

(file #54001, file #54002)
