With an old old Sun Nera server running very latest Debian sid I was
surprised to see :

FAIL: t-printf
PASS: t-scanf
PASS: t-locale
Testsuite summary for GNU MP 6.2.1
# TOTAL: 3

The ./tests/misc/t-printf.log says very little :
C_ceres$ wc -l ./tests/misc/t-printf.c
956 ./tests/misc/t-printf.c
C_ceres$
Just trying to run the test within gdb will throw a SIGSEGV :
(gdb) run

Looking at line 312 I see :
300
301 void
302 check_one (const char *want, const char *fmt, ...)
303 {
304va_list ap;
305va_start (ap, fmt);
306
307/* simplest first */
308check_vsprintf (want, fmt, ap);
309check_vfprintf (want, fmt, ap);
310check_vsnprintf (want, fmt, ap);
311check_vasprintf (want, fmt, ap);
312check_obstack_vprintf (want, fmt, ap);
313 }
314
This seems to be repeatable and also unlikely. I tried to single step
around in there and eventually ended up at :
obstack_free (h=0x7feefb8, obj=0x0) at obstack.c:350
I am likely doing something wrong here.
In any case the configure line was :
./configure ABI=64 --enable-cxx --prefix=/opt/bw
--libdir=/opt/bw/lib --disable-assembly --enable-shared
--enable-static --enable-fft
