Lilypond miscompiled on Fedora 17

[Pavel Roskin]

Hello!

I mentioned in passing that Fedora 17 (currently in beta) ships  
Lilypond 2.15.29 that reports bogus bar checks.

It turns out that both the current Lilypond from git and Lilypond  
2.14.2 are miscompiled on the up-to-date Fedora 17 so they exhibit the  
same problem.

That's the minimal example.  It doesn't report a bar check, but it  
shows an error:

\version "2.14.2"
\score {
  <<
    \new Staff { b2 }
    \new Staff { b1 }
  >>
  \layout {}
}

$ lilypond barcheck.ly
GNU LilyPond 2.15.38

Converting to `./barcheck.pdf'...

Attached is the output converted to png format.

Lilypond 2.14.2 reports the same error.

I tried compiling Lilypond with compat-gcc (version 3.4), but it  
doesn't understand some compiler flags needed by Python.
