See how large you can set the "save size" parameter.
Multiply by 10, or 100, or 1000... .
I'd say you are exploring to the boundaries of what XeTeX
is capable of doing.
save size won't go over 80,000 :(
OK.
But we don't need it now.
Here's the cause of the problem.
The package source xesearch.sty has a technical problem.
The macros \xs@String and \xs@Stack are used as variables,
repeatedly changing their expansions. However, sometimes the code
uses \edef\xs@String{...} but mostly it uses \xdef\xs@String{...}.
This mixture of local/global scope is what causes the loss of
string space, because an \edef instance requires the previous
\xdef
instance to be retained, not discarded. Then comes another \xdef
which may release the previous \edef's memory, but not that of the
\xdef prior to the \edef . Hence memory usage grows.
By making all instances become global, I now get your document to
finish, along with the Index page.
Here's the memory usage:
Here is how much of TeX's memory you used:
26092 strings out of 494542
451878 string characters out of 3157455
480737 words of memory out of 3000000
29083 multiletter control sequences out of
15000+200000
8574 words of font info for 51 fonts, out of
3000000 for 9000
669 hyphenation exceptions out of 8191
40i,7n,43p,1687b,9339s stack positions out of
5000i,500n,10000p,200000b,50000s
Here's the patch needed to modify xesearch.sty .
Does this look right?
This looks ok to me, except:
@@ -975,7 +975,7 @@
- \def\xs@String{#2}%
+ \gdef\xs@String{#2}%
@@ -983,7 +983,7 @@
- \def\xs@Stack{#2}%
+ \gdef\xs@Stack{#2}%
(I've turned \xdef into \gdef). Now, if your document works properly,
I'll release the patch.
Thanks again,
Paul
