Hi all,

I’m not sure this is a Luatex or Context bug so please feel free
to forward this to the appropriate ML if necessary.

With the latest standalone (Luatex beta-0.74.0-2012122510,
Context 2013.02.05 22:32) the font db builder fails at Adobe
Heiti as distributed with acroread:


    [14:33:17=>phg@phlegethon=> ~/tmp/ctx/fontdb] mtxrun --script fonts --reload
    <... />
    fonts           | names | adding path from OSFONTDIR: /home/phg/.fonts
    fonts           | names | globbing path /usr/share/fonts/**.otftexlua: ../../../source/texk/kpathsea/cnf.c:255: kpathsea_cnf_get: Assertion `kpse->program_name' failed.
    Aborted (core dumped)

(Full log attached.) All fonts, even Adobe stuff, up until Heiti
are processed without complaint. I traced the issue to a call to
fontloader.open() in font-syn.lua, line 221. To reproduce it, run
this code through texlua:

    #!/usr/bin/env texlua
    ff = fontloader.open[[/usr/share/fonts/adobe/AdobeHebrew_Regular.otf]] --> works
    print(ff) --> userdata
    ff = fontloader.open[[/usr/share/fonts/adobe/AdobeHeitiStd_Regular.otf]] --> fails
    print(ff)

The problem disappears if I initialize kpathsea first:

    kpse.set_program_name"texlua"
    ...

The problem does not occur with TeX Live 2012/Luatex 0.70/Context
2012.05.30 11:26.

Can anyone else reproduce this? Thanks.

Philipp
