Ruby

I'm using this Dockerfile to compile: https://github.com/docker-library/ruby/blob/ecbfdeb2b71e155222b1d3df0a33685247f00616/2.4/alpine3.6/Dockerfile, except with FROM resin/armhf-alpine (https://hub.docker.com/r/resin/armhf-alpine/) which forces docker to run through qemu with armhf emulation.

The compile is pretty standard:

&& autoconf \	&& gnuArch="$(dpkg-architecture --query DEB_BUILD_GNU_TYPE)" \ # the configure script does not detect isnan/isinf as macros	&& export ac_cv_func_isnan=yes ac_cv_func_isinf=yes \	&& ./configure \	--build="$gnuArch" \	--disable-install-doc \	--enable-shared \	&& make -j "$(nproc)" \	&& make install \ 

The above compiles without issues on am armhf and amd64 device, however when compiling through qemu armhf, it throws the following segmentation fault:

compiling util.c compiling variable.c compiling version.c compiling vm.c In file included from vm.c:293:0: vm_exec.c: In function 'vm_exec_core': vm_exec.c:83:18: warning: variable 'reg_pc' set but not used [-Wunused-but-set-variable] const VALUE *reg_pc; ^~~~~~ compiling vm_backtrace.c compiling vm_dump.c compiling vm_trace.c compiling ./missing/explicit_bzero.c compiling ./missing/setproctitle.c compiling addr2line.c compiling dmyenc.c compiling dln.c compiling localeinit.c compiling prelude.c compiling array.c compiling enc/ascii.c compiling enc/us_ascii.c compiling enc/unicode.c compiling enc/utf_8.c compiling enc/trans/newline.c vm.c: At top level: cc1: warning: unrecognized command line option '-Wno-self-assign' cc1: warning: unrecognized command line option '-Wno-constant-logical-operand' cc1: warning: unrecognized command line option '-Wno-parentheses-equality' linking miniruby generating encdb.h qemu: uncaught target signal 11 (Segmentation fault) - core dumped make: *** [uncommon.mk:854: encdb.h] Segmentation fault make: *** Waiting for unfinished jobs.... qemu: uncaught target signal 11 (Segmentation fault) - core dumped make: *** [uncommon.mk:643: .rbconfig.time] Segmentation fault 

Any ideas?
