https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71151
--- Comment #22 from Senthil Kumar Selvaraj ---
Confirmed that it's a linker issue related to adjusting reloc addends in the
presence of align directives. Found two separate bugs, will post patches later
this week.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71151
--- Comment #21 from Senthil Kumar Selvaraj ---
It occurs with "7.0.0 20160824 (experimental) (GCC)". Besides, the errors go
away if I remove --relax, so I think it's a linker issue.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71151
--- Comment #19 from Senthil Kumar Selvaraj ---
Can reproduce this on trunk with binutils master. Mostly likely a
binutils/linker bug, as turning off relaxation fixes the error. Will debug
further and post the conclusions.
