Source: plplot Version: 5.15.0+dfsg-9 Severity: normal Hello, looks like gcc compiler has some sort of bug (but the bug might be in the code), that makes the testsuite during build segfault if a -O3 is provided by the compiler.
This isn't a big deal for Debian users, because their gcc optimization level on ppc64el is -O2, but an user might have a different level while rebulding it, so I think it might be worth forcing a lower value or fixing the bug. "Patch" is following: --- plplot-5.15.0+dfsg/debian/rules 2019-11-30 19:16:24.000000000 +0100 +++ plplot-5.15.0+dfsg/debian/rules 2019-12-10 00:02:22.000000000 +0100 @@ -8,7 +8,12 @@ DEB_BUILD_MAINT_OPTIONS := hardening=+all DPKG_EXPORT_BUILDFLAGS := 1 +ifeq ($(DEB_HOST_ARCH), ppc64el) +DEB_CFLAGS_MAINT_APPEND := -fvisibility=hidden -O2 +else DEB_CFLAGS_MAINT_APPEND := -fvisibility=hidden +endif + DEB_FFLAGS_MAINT_APPEND := -fvisibility=hidden # Don't add -fvisibility=hidden to CXXFLAGS for now as this breaks the # octave bindings.
