| Summary | 0000026: Wrong calculation of some values | ||||
| Description | The attached zip is an extract of the Gregorio system for typesetting gregorian chant scores (http://home.gna.org/gregorio/). The bug happens with the file test.tex (plain LuaTeX), which includes the rather long gregoriotex.tex: it simply sets a single note on the score, but if we uncomment line 249 of gregoriotex (a simple \showthe command), the result is different. In results/ I've attached the two possible results, when uncommenting the \showte command (test-showthe.pdf) and commenting it out (test-commented.pdf). | ||||
| Additional Information | Sorry I can't be more precise, but the bug seems to be quite real, and independent of the architecture or the LuaTeX version. It has been reported to me by Élie Roux (elie.roux@enst-bretagne.fr), the Gregorio author. | ||||
| Tags | No tags attached. | ||||

Élie just confirmed that the intended result is the one with the \showthe commend. Incidentally, replacing that command with something unrelated to calculations, like a \message{Hello world} gives the same (correct) result. |

I've just discovered that this bug is not only in omega, aleph and luatex, but also in tex... http://norgz.info/bug.zip << here are two tex files to reproduce the bug : gregorio-good and gregorio-bad only differ in one \showthe, and yet the result is different... Where can I bugreport that ? Could someone help me fixing it ? Thank you, -- Elie |

This: \global\isonaline=\number 0\iftrue1\fi assigns 1 because the \if... is still part of the assignment. Removing the % at the end of line 172 \global\isonaline=\number 0% fixes the wrong output. Best wishes, Taco |
