| Summary | 0000923: strange minus value appearing randomly when attribute is unset and immediate write is called | ||||
| Description | Following example \attribute0=-"7FFFFFFF\relax \immediate\write-1{Anything} \immediate\write-1{Anything} \skip0=1pt plus 100pt\relax \showthe\skip0 \bye outputs 1.0pt plus 100.0pt minus 0.00002pt. while \skip0=1pt plus 100pt\relax \showthe\skip0 \bye outputs 1.0pt plus 100.0pt minus 0.00002pt. | ||||

Sorry, the second outputs 1.0pt plus 100.0pt. (which is correct, unlike the other) |

Thank you for the report. We are investigating. |
|
|
The creation of certain whatsit nodes seems to increment the minus part of the constant zero gluespec so it is cummulative. Each write creates a node. A workaround is to set the zero attribute to some value before the first write. (FWIW: in context attr zero always has a value which is why it went unnoticed.) |

Fixed in the upcoming 0.80 (TexLive 2015) |
