Subject: t/02bad_deriv.t fails on Debian/stretch
On my Debian/stretch smoker I see the following failure: ... # Failed test at t/02bad_deriv.t line 50. # Looks like you failed 1 test of 13. t/02bad_deriv.t .. Dubious, test returned 1 (wstat 256, 0x100) Failed 1/13 subtests ... Tests pass on older Debian systems (jessie, wheezy).

How is your perl built? Especially do the linker flags contain "-pie" option? I run into similar failure with the option <https://bugzilla.redhat.com/show_bug.cgi?id=1242769#c4>.

It does not seem so. Here's an excerpt from perl -V (perl-5.27.9): Linker and Libraries: ld='cc' ldflags =' -fstack-protector-strong -L/usr/local/lib' libpth=/usr/local/lib /usr/lib/gcc/x86_64-linux-gnu/6/include-fixed /usr/include/x86_64-linux-gnu /usr/lib /lib/x86_64-linux-gnu /lib/../lib /usr/lib/x86_64-linux-gnu /usr/lib/../lib /lib libs=-lpthread -lnsl -lgdbm -ldb -ldl -lm -lcrypt -lutil -lc -lgdbm_compat perllibs=-lpthread -lnsl -ldl -lm -lcrypt -lutil -lc libc=libc-2.24.so so=so useshrplib=false libperl=libperl.a gnulibc_version='2.24' Dynamic Linking: dlsrc=dl_dlopen.xs dlext=so d_dlsymun=undef ccdlflags='-Wl,-E' cccdlflags='-fPIC' lddlflags='-shared -O2 -L/usr/local/lib -fstack-protector-strong'

It also fails on Ubuntu 18.04 (bionic).

If the failing test is rewritten to use cmp_ok instead of ok: diff --git a/t/02bad_deriv.t b/t/02bad_deriv.t index dfa613e..b5ec5ed 100644 --- a/t/02bad_deriv.t +++ b/t/02bad_deriv.t @@ -47,7 +47,7 @@ my @eps = (1.00, 0.10, 1.000, 0.100); foreach my $par (0..$#parameters) { my $v = $parameters[$par][1]; ok(defined $v); - ok($v + $eps[$par] > $val[$par]); - ok($v - $eps[$par] < $val[$par]); + cmp_ok($v + $eps[$par], ">", $val[$par]); + cmp_ok($v - $eps[$par], "<", $val[$par]); } then the test suite fails with a little more diagnostics: t/02bad_deriv.t .. 1/13 # Failed test at t/02bad_deriv.t line 50. # '5' # > # '5.15' # Looks like you failed 1 test of 13. t/02bad_deriv.t ..
