Update of bug #43220 (project octave):
Assigned to: None => mtmiller
Operating System: Mac OS => Any

Follow-up Comment #5:
Yes, I have the same values.
The two configure output files are config.status and config.h, here's what I
have in an unmodified configure of Octave:
$ grep -i signbit config.h
/* #undef DBL_SIGNBIT_BIT */
/* #undef DBL_SIGNBIT_WORD */
/* #undef FLT_SIGNBIT_BIT */
/* #undef FLT_SIGNBIT_WORD */
/* Define to 1 when the gnulib module signbit should be tested. */
#define GNULIB_TEST_SIGNBIT 1
/* Define to 1 if <cmath> provides signbit. */
#define HAVE_CMATH_SIGNBIT 1
/* Define to 1 if <cmath> provides float variant of signbit. */
#define HAVE_CMATH_SIGNBITF 1
/* Define to 1 if you have the declaration of `signbit', and to 0 if you
#define HAVE_DECL_SIGNBIT 1
/* Define to 1 if you have the `signbit' function. */
/* #undef HAVE_SIGNBIT */
/* #undef LDBL_SIGNBIT_BIT */
/* #undef LDBL_SIGNBIT_WORD */
$ grep -i signbit config.status
S["REPLACE_SIGNBIT_USING_GCC"]="1"
S["REPLACE_SIGNBIT"]="0"
S["GNULIB_SIGNBIT"]="1"
D["GNULIB_TEST_SIGNBIT"]=" 1"
D["HAVE_CMATH_SIGNBIT"]=" 1"
D["HAVE_CMATH_SIGNBITF"]=" 1"
D["HAVE_DECL_SIGNBIT"]=" 1"
It's possible that a bug was introduced in SuiteSparse 4.3.x, but I only have
4.2.x and 4.4.x easily available to me to test with. If it's possible for you
to upgrade to 4.4.x, I would try that first and see if the error is resolved.
