[tex-live] TL 2011 Segmentation fault xelatex

[Karl Berry]

Hi Pander,

    Attached is the document that creates the segmentation fault.
    [segfault.tar.gz, running with xelatex]

Sorry it's taken a ridiculous amount of time to get back to this.
Unfortunately I cannot reproduce the problem, most likely because the
document assumes the various fonts are available in the OS:
! The font "TeX Gyre Pagella" cannot be found.
! The font "FreeSans" cannot be found.

As a result, not much happens when running, and there is no crash.

Can you change the document so that the fonts are looked up (by
filename) in the TL tree instead and see if the crash still happens?
Depending on where the bug is, it might or it might not ...

Thanks,
Karl


P.S. As an aside, it seems there have been incompatible changes since
the TL'11 release in etoolbox and/or other packages.  
What I see are these errors while loading polyglossia.sty:

! Undefined control sequence.
l.402 \define at boolkey

! Package etoolbox Error: Boolean '\ifxpg at localmarks' undefined.

Sigh.  (These errors don't happen with the original TL'11 release.)
