emacs is highly sensitive to the order and structure of executables
|
|
produced by the linker. This is an artifact of its undumping mechanism
|
|
(essentially starts emacs, loads a bunch of stuff, core dumps, then
|
|
turns the core dump into a new executable).
|
|
|
|
We've seen a lot of pain around this for ppc64le as well as after the
|
|
RELRO improvements we made to binutils/ld over the last 6 months.
|
|
|
|
ISTM that the testing plans for RHEL going forward ought to include a
|
|
test build of emacs with the new binutils installed. No further tests
|
|
are necessary since the build process for emacs exercises the
|
|
problematic bits.
