hi thomas,

w/ 'out of the box' lynx2.8.6dev.17.tar.gz, i reproducibly get the:

        "internal error while caching 1st tagspec of 0 lexeme"

error on execute.

i tried various CFLAG debug (-g on/off) & optimization level (-O, -O1,
- -O2, -O3) combos ... alas, no change.

after examining:

        diff -u LYPrettySrc.c_ORIG LYPrettySrc.c_MOD

and noting 'nothing earthshattering', i started cycling through
step-by-step changes ... and found that simply adding/changing *one*
item, i.e.:

===========================================================
${EDITOR} src/LYPrettySrc.c

@@ -187,7 +187,10 @@
             HT_tagspec *head = NULL, *tail = NULL;
             HT_tagspec **slot = (isstart ? lexeme_start : lexeme_end) + lexeme;
        
             while (!stop) {
+++             CTRACE((tfp, "...state %d\n", state));
                switch (state) {
===========================================================

is sufficient for the error to vanish ...  i.e., lynx operates as normal.

as for 'valgrind' ... have to figure out what *it* does to be able to
figure out what you specifically want done on OSX.  i have a fairly
complete set of dev tools ... just a matter of getting a handle on what
is happening here :-/

cheers,
