Is the problem resolved? Because I too had faced similar problems while
exporting to PDF.

I think it might be a good idea to verify if the OTCs is fine on OS X and the
multilingual OTFs are fine on Windows and OS X, as shown in the flowchart

Committed attachment 103925 now without noticing comment 19.  Anyway, the
change as-is should be especially good enough as a hotfix for older versions,
so requested backports now to libreoffice-4-2 towards LO 4.2.7
(https://gerrit.libreoffice.org/#/c/10746/) and to libreoffice-4-3 towards LO
4.3.1 (https://gerrit.libreoffice.org/#/c/10745/).  Please continue on master
with any improvements as discussed in comment 19.

--- Comment #16 from Audrey Tang audr...@audreyt.org ---
It turns out the 16-256 FDArray count limit increase is correct (as in my
patch), because per spec the max allowed FDArray count is 256.

More info from @kenlunde, main coordinator of Source Han Sans CJK:

Source Han Sans (and thus Noto Sans CJK) include 19 FDArray elements. The
maximum number of FDArray elements is 256. For testing fodder, please grab one
or most fonts that are provided in the following CJK Type Blog article that
@kenlunde published over two years ago:
http://blogs.adobe.com/CCJKType/2012/05/all-unicode-cfr.html

Since some devs might be in vacation, would it be possible you send a message
on dev mailing list? (see

--- Comment #19 from Michael Stahl mst...@redhat.com ---
hi Audrey,

the patch is looking good and should fix the crash for this particular font.

but it raises the question: why does this actually crash, and not
just fail to read the font?  clearly crashing when reading
potentially untrusted input is a bad idea...

i'd suggest to turn the assert from
http://docs.libreoffice.org/vcl/html/cff_8cxx_source.html#l01504
into a real check and to cap the mnFDAryCount to the array size.

also, can you please send a license mail to
 libreoff...@lists.freedesktop.org
as described on this page:

https://wiki.documentfoundation.org/Development/Developers#Example_Statement

feel free to add an entry for yourself on the page too.

--- Comment #20 from Audrey Tang audr...@audreyt.org ---
Re assert(), I'd like to defer it to devs more versed in the error handling
paradigm; IMHO it's unlikely that a font containing 256 FDArray will get used
to the PDF export stage, as it probably won't render in the first place.

Re license. I've just edited the Wiki and sent this CC0 Universal Decalaration:

To the extent possible under law, I waive all copyright and related or
neighboring rights to my past  future contributions to LibreOffice.

--- Comment #13 from Audrey Tang audr...@audreyt.org ---
From the stack trace at https://bugs.freedesktop.org/attachment.cgi?id=103122
it looks like assert from
http://docs.libreoffice.org/vcl/html/cff_8cxx_source.html#l01504 because
maCffLocal is declared to 16 at
http://docs.libreoffice.org/vcl/html/cff_8cxx_source.html#l00363 but
mnFDAryCount requires more than 16 local CFFs.

Would extending 16 to 256 (or make it dynamically allocated) alleviate the
problem?

showing a problem in vcl/source/fontsubset/cff.cxx)

Does the crash occur with the OTC or the OTF versions of the fonts
installed?

Ie, a single file per weight or several per?

It is possible that something doesn't yet support OTC-style fonts.

I downloaded the zip file indicated in description, this one contained only otf
files:
SourceHanSansCN-Bold.otf
SourceHanSansCN-ExtraLight.otf
SourceHanSansCN-Heavy.otf
SourceHanSansCN-Light.otf
SourceHanSansCN-Medium.otf
SourceHanSansCN-Normal.otf
SourceHanSansCN-Regular.otf

Sorry.

I was following only via email; I didn’t have the initial post at hand when I
replied.

I only have the OTC version loaded.

With version:

   LibreOffice 4.2.1.1 420m0(Build:1)

it fails to scale the non-latin glyphs to the same size as the latin glyphs
when specifying Source Han Sans SC Medium.

These fonts have about as many glyphs as an SFNT can have.  Perhaps the
FontSubsetInfo::CreateFontSubsetFromCff() code doesn’t support fonts with so
many glyphs?
