Dear TeX(-k) people, dear pdfTeX team, late last year Norbert Preining already asked on the TeXk list about a problem encountered in Debian, namely a TeX capacity exceeded error on grouping levels. Nobody could help back then, but now someone started to analyse this further (many thanks, Stijn!). So could you please (again) have a look? It seems the value is hardcoded in the sources, "Stijn van Drongelen" <tinctorius(a)gmail.com> wrote: > The issue seems to have its roots in build/source/texk/web2c/tex.web, > line 5925-5930: > > if cur_level=max_quarterword then overflow("grouping levels", > @:TeX capacity exceeded grouping levels}{\quad grouping levels@> > max_quarterword-min_quarterword); > {quit if |(cur_level+1)| is too big to be stored in |eqtb|} > cur_boundary:=save_ptr; incr(cur_level); incr(save_ptr); cur_group:=c; > end; > > So if 'cur_level' exceeds the maximum quarterword size, TeX dies. > These constants are defined in 2411-2414: > > @d min_quarterword=0 {smallest allowable value in a |quarterword|} > @d max_quarterword=255 {largest allowable value in a |quarterword|} > @d min_halfword==0 {smallest allowable value in a |halfword|} > @d max_halfword==65535 {largest allowable value in a |halfword|} > > And on line 2409, it says: "The values defined here are recommended > for most 32-bit computers." > > I use amd64.

There is a configuration variable nest_size level, but it doesn't seem to help in this case: The attached file gives an error ! TeX capacity exceeded, sorry [grouping levels=255]. although my texmf.cnf has nest_size=500. Should/can we change max_quarterword, or are there side effects? Or should the grouping levels instead use halfword? Or would you like to do it in a completely different way? This is a real life problem which affects building the PostgreSQL documentatin. Many thanks in advance, Frank -- Frank Küster Debian Developer (teTeX/TeXLive)

[pdftex-Bugs][993] /Names array not sorted correctly

Bugs item #993, was opened at 2008-05-24 13:24 Status: Open Priority: 3 Submitted By: Martin Schröder (oneiros) Assigned to: The Thanh Han (hanthethanh) Summary: /Names array not sorted correctly Resolution: None Group: v1.40.6 Category: None Initial Comment: Axel Berger and Heiko Oberdiek report an error with the sorting of the /Names array: /Names [(cite.Kr07) 44 0 R (cite.Li08) 45 0 R (cite.M\37403) 23 0 R (cite.Mi00) 47 0 R (cite.Mi84) 48 0 R (cite.Mo04) 50 0 R] "cite.Mü03" (= "cite.M\37403") should come after "cite.Mo04". A test file with output is attached. ---------------------------------------------------------------------- >Comment By: The Thanh Han (hanthethanh) Date: 2008-05-27 16:48 Message: ok then this should be fixed as the spec says. BTW, it doesn't really solve the reported problem (ü will come after eg z). ---------------------------------------------------------------------- Comment By: Hans Hagen (hagen) Date: 2008-05-27 16:03 Message: the spec says: The Names entries in the leaf (or root) nodes contain the tree’s keys and their associated values, arranged in key-value pairs and sorted lexically in ascending order by key. Shorter keys appear before longer ones beginning with the same byte sequence. The encoding of the keys is immaterial as long as it is self-consistent; keys are compared for equality on a simple byte-by-byte basis. so, it's just bytes ---------------------------------------------------------------------- Comment By: The Thanh Han (hanthethanh) Date: 2008-05-27 15:43 Message: this is a problem, but it's not clear to me how it should be fixed. Assume that we translate "\374" to the corresponding charcode (0374 = 252) before sorting, then how we decide the lexicographic order of that char? it can be intepreted as ü but also can be eg ytilde or something different, depending on the encoding we use. Comments? ---------------------------------------------------------------------- You can respond by visiting: http://sarovar.org/tracker/?func=detail&atid=493&aid=993&group_id=106
