After upgrade to luaTeX Version 3.141592-beta-0.10.2:

Following code works as expected.
Commented lines (everyone) still cause context/luatex to end its job
without error message, pdf and log.
Some font gives warning about features that go out of bounds, but still
works fine.

What version of the dejavu fonts do you use, exactly? These fonts
are a little rough around the edges as well as being in active
delopment, so it is a hard target to test against. Over here,
all of the fonts in release 2.19 them worked ok in luatex 0.10.2
(on linux)

Best wishes, Taco

I use release 2.19 too and luatex 0.10.2 on linux too.

# luatex -v
This is luaTeX, Version 3.141592-beta-0.10.2-2007081408

"pokus2.tex"

That ends with "Segmentation fault", what is probably the point.

I tried to recompile luatex double checking that no CFLAGS are set, but
got the same result.


...but if nobody except me uses dejavu fonts or have these troubles, I
can choose other fonts. There are probably more crucial things to
bother about.


Anyway, thanks for interest.

As usual, I am running a slightly newer version of context

   ConTeXt  ver: 2007.08.15 11:52 MKIV  fmt: 2007.8.15  int:

and perhaps that makes a difference (you have to wait for the next
context release to test that).

But otherwise, I have the same versions you have, and the document
compiles correctly, making it impossible for me to investigate this
further.

I _do_ want every font to work (or at least not segfault), but I
really do need to be able to reproduce an error before being able
to fix it. As it stands, there is nothing I can do.

Best wishes,
Taco

Re: dejavu

[zs]

Another hint:

I tried to cut off some less common (from my point of view) glyphs from
dejavusanscondensed font using fontforge.
After that slimming, everything seems to work.

Result: at some circumstances, some glyphs in some fonts may cause
crash of luatex.

If anyone interested, here is the reduced font:

Re: dejavu

[zs]

I know, people who tried to reproduce my trouble with DejaVu fonts
"failed" :-)

Nevertheless I'm now giving my solution to the public, just in case
somebody in future gets the same failure.

I found, if glyph uni05C7 at position 1479 is cleared using fontforge,
everything works fine.
