Description Nick Bowler 2024-09-26 02:56:00 UTC
Hi,

The afl-fuzz man page installed by the aflplusplus ebuild is badly damaged.
For example:

  % man afl-fuzz | head
  afl-fuzz(8)             System Manager’s Manual            afl-fuzz(8)

  NAME
         afl-fuzz

  SYNOPSIS
         [1;93m[!]  [1;97mWARNING:  [0mPotentially mistyped AFL environ‐
         ment variable: USE_EXPAND_IMPLICIT=ARCH ELIBC KERNEL,  did  you
         mean AFL_USE_EXPAND_IMPLICIT=ARCH ELIBC KERNEL?[0m

(there is about about half a page of garbage in total, not all shown here).

What seems to be happening is that the afl-fuzz program itself will barf ANSI
rainbow vomit to standard output whenever it is run with any variables whose
names begin with USE_ (including the underscore) in the environment.  I guess
the build system runs afl-fuzz to generate the man page and then just copies
all that garbage straight into the generated troff code, control characters
and all.

Of course, the ebuild environment has many such variables defined so we end up
with a half page of line noise.  In order to get a (mostly) usable man page it
suffices to unset the problematic vars when building (note that it is not
enough to just set them to empty: they must be removed from the environment).
