I did a clean minimals install on my Windows XP Home SP3 system and get the same strange output.

ConTeXt ver: 2008.11.10 21:40 MKIV fmt: 2008.12.22 int: english/english This is LuaTeX, Version snapshot-0.31.2-2008121200, build 1659

C:\context\tex\texmf\fonts\opentype\public\lm\lmroman12-regular.otf

mailed to Taco.

Thanks, got them. More later, but at first glance the tma does not look all that weird.

Short update on the files people sent me: * the otf file is identical, * the tma and tmc seem fine It seems that somehow, when the tmc is read in, context (i.e. luatex) misinterprets the numeric values in the bytecode completely, resulting in ridiculous values for character widths, heights, depths etc. I am afraid I still have no idea why this happens. Best wishes, Taco

Hi, all

Can I roll back and use the old version when context isn't broken? I have several documents which need to be processed ASAP. Thanks.

Hello Fengan, you need both an older version of luatex and an older version of ConTeXt. Suggestion 1: You can download mswincontext.zip from PRAGMA, though that one dates months back. If that is not an issue, you can use that one. Suggestion 2: Change first-setup.bat, so that --context=beta switch will read --context=2008.10.31 and run first-setup.bat again. This will give you the version of ConTeXt that's still OK, but the same broken LuaTeX, so you need to download some older version of luatex binary from http://foundry.supelec.fr/projects/luatex (0.30.3 should be fine). You need to delete the contents of texmf-cache and regenerate formats. I would like to fix this, but I don't know how. One option is to revert both ConTeXt and LuaTeX to an older version. A much better thing would be to fix font-otf.lua. Hans? Taco? Mojca

I can almost certainly reproduce this, I see an uninitialized variable in valgrind.

Nope, couldn't do it. I am _almost_ sorry to say that luatex on linux-64 is behaving fine. Mojca (or someone else that has this 'Parsing CFF' problem), can you try to pinpoint the problem in a debugger? Best wishes, Taco

Which debugger Taco ?

A source debugger (like gdb). You'll also need to comment out the "$STRIP "$B"/texk/web2c/luatex" line in build.sh, otherwise the debugger cannot use symbols. The message is produced by font/writecff.c, line 820: pdftex_fail("Parsing CFF DICT failed. (error=%d)", status); you can set a breakpoint there, but the error happens earlier. The (error=-1) actually signifies a CFF parsing (decoding) error, but that does not help much in finding the problem. What is needed is at least a stack backtrace, and probably also the current location inside the CFF file. Best wishes, Taco

After lots and lots of debugging work by Mojca, the problem itself turned out to be simple (as is usually the case). This bug surfaces always and only when your locale is set to using a comma for the decimal separator in numbers. It turns out that the bug was already 'mechanically' fixed in the development trunk, and that explains why Hans was not affected (my own locale is "C"). Luatex 0.31.3 will be released on monday. Best wishes, Taco

I just installed ConTeXtMinimal using first-setup.bat. But it seems it has some serious bug that context even couldn't deal with such a easy document:

\starttext Hello world! \stoptext

What's the problem? Anybody can help me?

I got the same error so I tried texexec instead of context and it seems to work fine. How different is context from texexec?

Oops dumb question on my part... did not realise that texexec used pdfTeX by default and context uses luaTeX. ... Derek
