<div dir="ltr">I did some tests based on Debian's TeX Live 2018. I could reproduce the difference with Patrick's plain LuaTeX example: with luatex 1.07.0, the example gives "torn by" on one line. With luatex compiled from the latest trunk version, there is a linebreak after "torn".<br> <br>According to my tests the offending commit is revision 7009 "disable-dump-share by default" on the experimental branch. This is a small commit that simply changes a build flag:<br><br>diff --git a/build.sh b/build.sh<br>index 8b2244fb3..fa67daefe 100755<br>--- a/build.sh<br>+++ b/build.sh<br>@@ -308,7 +308,7 @@ TL_MAKE=$MAKE ../source/configure $TEXLIVEOPT $CONFHOST $CONFBUILD $WARNINGFLA<br> --disable-largefile \<br> --disable-xetex \<br> --disable-ipc \<br>- --enable-dump-share \<br>+ --disable-dump-share \<br> --enable-coremp \<br> --enable-web2c \<br> $LUA53ENABLE $JITENABLE \<br><br>I tried reverting to "--enable-dump-share" on the latest trunk branch, and indeed I then get the same output as with luatex 1.07.0...<br>
