Source: ruby2.5 Severity: normal User: debian-sup...@lists.debian.org Usertags: sh4
Hello! Due to a compiler bug in gcc-9 and newer, ruby2.5 (and ruby2.7) currently gets miscompiled and crashes with an 'Illegal Instruction' error [1]. The problem can be easily worked around by passing -fno-crossjumping through CFLAGS to the compiler. Could you include the small attached workaround in the next upload of ruby2.5 (and ruby2.7) to fix the build on sh4 until the compiler bug has been fixed upstream? diff -Nru old/ruby2.5-2.5.7/debian/rules new/ruby2.5-2.5.7/debian/rules --- old/ruby2.5-2.5.7/debian/rules 2019-10-23 17:48:04.000000000 +0200 +++ new/ruby2.5-2.5.7/debian/rules 2020-02-20 15:17:13.910784900 +0100 @@ -55,6 +55,11 @@ export DEB_BUILD_MAINT_OPTIONS = hardening=+bindnow configure_options += $(shell dpkg-buildflags --export=configure) +# See: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93808 +ifneq (,$(filter $(DEB_HOST_ARCH),sh3 sh4)) +export DEB_CFLAGS_MAINT_APPEND += -fno-crossjumping +endif + # Always build with /bin/bash, to get consistent rbconfig.rb (which embeds SHELL). export SHELL := /bin/bash Thanks, Adrian > [1] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93808 -- .''`.
