[PATCH] Assertion `iter->cur.wc == 0' failed.

[Rob Landley]

Still trying to build Linux From Scratch 6.7 packages against the last uClibc 
stable release, and I hit this strange assertion breaking "shadow" build:

# find man -name Makefile.in -exec sed -i 's/groups\.1 / /' {} \;
find: mbuiter.h: 171: mbuiter_multi_next: Assertion `iter->cur.wc == 0' failed.

That's not the busybox "find" breaking, that's the findutils one installed by an 
earlier part of the LFS build.  So I worked around it by rephrasing the LFS 
instructions to "find | xargs" and continued on, and then the texinfo build 
died with:

..//makeinfo/makeinfo: mbuiter.h: 171: mbuiter_multi_next: Assertion `iter-
>cur.wc == 0' failed.

Which is a pattern.  So I googled, and found this:

  http://bugs.gentoo.org/show_bug.cgi?format=multiple&id=288743

What I learned from that is:

  1) This has been a known bug in gentoo for over a year now.
  2) Their fix is to back off to 0.9.28.

What I also happen to know is that the uClibc repository is an extremely 
unpleasant thing to try to git bisect because half the commits between release 
versions don't even _compile_, let alone let you build packages against them.

Does anyone have an opinion on this?  (Other than "why the hell is the FSF 
force-inlining a 59-line C function", because if they weren't crazy there 
wouldn't be much need for uClibc or busybox...)  I really don't know anything 
about internationalization, and am thus not the best candidate to try to make 
it work.  That said, it's been more or less stagnant since 2003 (and 
completely stagnant since 2005) while everybody fails to put out a release 
containing NPTL, so I guess if I want it to work I'll have to fix it myself.

(I'm tempted to just install http://penma.de/code/gettext-stub/ and see how 
far I get with that, but it was a one line fix.  Attached.)
