Here’s a standalone reproducer:
(use-modules (texinfo)
(sxml simple)
(ice-9 threads))
(define sequential? (getenv "SEQUENTIAL"))
(define (for-each/maybe-parallel proc lst)
(if (pk 'sequential? sequential?)
(for-each proc lst)
(n-par-for-each 6 proc lst)))
(setvbuf (current-output-port) 'none)
(for-each/maybe-parallel
(lambda (str)
(catch 'parser-error
(lambda ()
(texi-fragment->stexi str))
(lambda args
(pk 'bah! args '<<>> str)
(error "failed"))))
(make-list 5000 "Hello @code{world}, this is @emph{Texinfo}."))
It turned out that (sxml ssax input-parse) would reuse the same global
buffer for each call to ‘next-token’ and ‘next-token-of’ (the Texinfo
parser uses the latter).
Fixed in 3b42b1eb526a85e4fac772e1837046e56e3b9bdc.
