[Bug 936563] openssl build failure due to debugedit segfault on ppc64le

http://bugzilla.suse.com/show_bug.cgi?id=936563 http://bugzilla.suse.com/show_bug.cgi?id=936563#c7 --- Comment #7 from Michel Normand --- current_status: As suggested by Ulrich Weigand use readelf that reports warning message (1) about DW_FORM_strp that is associated to form processed by debugedit at time of segfault (2) Then identify the related object ecp_nistp224.o (3) source of these warnings. The related C file is compiled without any warning (4) Need to continue investigation from here === (1) [michel@twppc64le:~/work/Base:System/openssl] $readelf -wi /mnt/disk3/build-root/standard-ppc64le/home/abuild/rpmbuild/BUILDROOT/openssl-1.0.2c-0.ppc64le/lib64/libcrypto.so.1.0.0
