Subject: [PATCH] Drop gnulib no-abort.patch
|
|
|
|
Originally added in db7337a3d353a817ffe9eb4a3702120527100be9, this
|
|
patched out all relevant invocations of abort() in gnulib. While it was
|
|
not documented why at the time, testing suggests that there's no abort()
|
|
implementation available for gnulib to use.
|
|
|
|
gnulib's position is that the use of abort() is correct here, since it
|
|
happens when input violates a "shall" from POSIX. Additionally, the
|
|
code in question is probably not reachable. Since abort() is more
|
|
friendly to user-space, they prefer to make no change, so we can just
|
|
carry a define instead. (Suggested by Paul Eggert.)
|
|
