[Octave-bug-tracker] [bug #46449] Address-sanitizer triggered in scripts/sparse/ichol.m

[Robert Jenssen]

Follow-up Comment #5, bug #46449 (project octave):

Better is, in autoconf.ac:


### Add address-sanitizer checking
AC_MSG_CHECKING(for --with-address-sanitizer)
AC_ARG_WITH(address-sanitizer,
            AS_HELP_STRING([--with-address-sanitizer],
                           [add Address-Sanitizer checking]),
[
AC_MSG_RESULT($withval)
XTRA_CFLAGS="-g -fsanitize=address -fno-omit-frame-pointer $XTRA_CFLAGS"
XTRA_CXXFLAGS="-g -fsanitize=address -fno-omit-frame-pointer $XTRA_CXXFLAGS"
LDFLAGS="-g -fsanitize=address $LDFLAGS"
],
[AC_MSG_RESULT(no)])


Then running the following gives a stack trace with line numbers, attached.


ASAN_OPTIONS=symbolize=1 ASAN_SYMBOLIZER_PATH=llvm-symbolizer make check
