Strange problem with EBGaramond st ligature and 20150901 beta
Please help with the strangest problem I have come across. The following document fails (does not complete, hangs) when the following conditions hold: * ConTeXt ver: 2015.09.01 11:10 MKIV beta fmt: 2015.9.3 int: english/english * \mainlanguage[en] or fr * Font EBGaramond otf from EBGaramond-0.016.zip https://bitbucket.org/georgd/eb-garamond/downloads * Font features clig and hlig * Font style \it or \sl * Text string (among others) astro istar istra ister istor istro istur The problem is the same with \usemodule[newotf] and without. The problem does not occur with: * ConTeXt ver: 2015.08.30 17:07 MKIV beta fmt: 2015.8.30 int: english/english. * \mainlanguage la or de. * \tf or \sc or \bd (there is no bold in the font). The issue appears to be related to the st ligature, but only in conjunction with some other letters. Can somebody else reproduce the problem. For the record, this is running on Windows 10 Pro 64-bit. The problem document: \definefontfeature [ff:ebg][default][ clig=yes,hlig=yes, %% 1 %% ] \definefontfamily [mainface][serif][ebgaramond] [features=ff:ebg] \setupbodyfont [mainface] % \mainlanguage[la] %% 2 %% \mainlanguage[fr] %% 3 %% \starttext \it %% 4 %% % \tf %% 5 %% astro %% 6 %% % aStro %% 7 %% % asTor %% 8 %% \stoptext -- Rik

more in conjunction with hyphenation
Can somebody else reproduce the problem. For the record, this is running on Windows 10 Pro 64-bit.
The problem document:
\definefontfeature [ff:ebg][default][ clig=yes,hlig=yes, %% 1 %% ] \definefontfamily [mainface][serif][ebgaramond] [features=ff:ebg] \setupbodyfont [mainface] % \mainlanguage[la] %% 2 %% \mainlanguage[fr] %% 3 %% \starttext \it %% 4 %% % \tf %% 5 %% astro %% 6 %% % aStro %% 7 %% % asTor %% 8 %% \stoptext
There is indeed a loop there. I uploaded a fixed version. Recently Kai and I have upgraded the fonthandler with respect to ligature (contextual) and kerning which is sort of messy given the different approaches that font use for dealing with ligatures. This is normally no issue but interferes badly with hyphenation. The new font handler (m-newotf) is also updated and has a bit better performance (and I have a local experimental variant that is again somewhat faster (15%) but that depends on a few more pending luatex helpers).
