looks ok in context so it's probably a latex bug (some math parameter wrong) |
|
|
Happens with this plain document as well: $\displaystyle\sqrt{\sum_{i=0}^n}$ \bye |
|

Looks ok here when run with luatex-plain: luatex -ini=luatex-plain luatex -fmt=./luatex-plain so, best define 'plain'. Keep in mind that plain is really 'plain.tex' i.e. traditional fonts and math. The luatex-plain format only adds basic otf support. There is a radical primitive that could be used to redefine the sqrt command in plain but then we're no longer talking 'plain'. |

What do I have to type on the command line in order to check the behavior under luatex-plain? Running luatex -ini=luatex-plain test.tex where test.tex contains "$\displaystyle\sqrt{\sum_{i=0}^n}$\bye" gives the same wrong result with the black box. Running "luatex -fmt=./luatex-plain test.tex" results in "kpathsea: Running mktexfmt ./luatex-plain.fmt I can't find the format file `./luatex-plain.fmt'!" Please let me know if I missed something. I will try to reproduce what you did once I have the full command line. |

output looks fine with my version of luatex-plain. It looks to me like a misconfiguration of the macro package, not an engine error. |
