My head -r339076 based powerpc64 and armv7 contexts also fail for: # /libexec/ld-elf.so.1 /bin/ls The armv7 (a Cortext-A7 context) is interestingly different in how it fails: # /libexec/ld-elf.so.1 /bin/ls ld-elf.so.1: /bin/ls: mmap of entire address space failed: Cannot allocate memory My aarch64 context (a Cortext-A53 context) had no problem. (All 3 examples are without any of the the recent updates or patches to ld-elf.so.1 source code.) === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
