Some non-deterministic behaviour i luatex
by Lars Hamren 15 Sep '16

15 Sep '16

Hej, I started running the context test suite as a regression test to verify that my local changes don't introduce any errors. I got LOTS of errors. While I may have introduced som errors, I really couldn't have introduced THAT many errors. Testing was also somewhat erratic. Sometimes things worked, sometimes not. So I then ran the test suite using the unmodified standalone context, with the original binary. I ran the test suite eight times, and then compared each run with the previous, so there are seven comparisons for each test. For each test, I then counted the number that were different. Ideally, there should either be no differences, or, if the test uses random numbers, seven differences. But there are a number of tests that generate between one and six errors. In total, 324 of the tests do not consistently generate identical output. I have put an archive of context diffs less than 100k is size here: http://www.sdu.se/pub/luatex/ There is also the script that I use to compare two runs on the test suite. Note that I remove a few lines that always differ. In addition I remove some XML lines. Each test is run like this context --silent --result=/path/to/output/01/cld/functions-001.pdf functions-001.tex I have identified a few different errors, and will describe them in separate posts. /Lars ------------------------------------------------------------------- Lars Hamrén WWW...: www.sdu.se Vadmöllan 211 Mobile: +46(705)189090 S-225 94 Lund Sweden

invalid list tail
by Benjamin Desef 14 Sep '16

14 Sep '16

Hi, I just came up with an error using microtype and the fourier font package. Robert Schlicht (maintainer of microtype) adviced me to send the bug report here, since he cannot not reproduce the bug in LuaTeX 0.95; my version is 0.98.4 from MikTeX NEXT.MWE: \documentclass{article} \usepackage{fourier, microtype} \begin{document} particle $\infty$\end{document} This willcompile fine with pdfLaTeX and apparently older LuaLaTeX versions, but the most recent will give the error (complete log isattached) ! error: (linebreak): invalid list tail,probably missing glue! ==> Fatal error occurred, no output PDFfile produced! The errorseems to critically depend on the word before the math symbol – if I change itto “Test”, everything works. I also tried inverting the order of loading.In mydocuments, I use Fourier only for text mode; if instead of loading the package,I just say \renewcommand{\rmdefault}{futs}, the error still persists. And even if I turn out everything [activate=false], it still is there. Benjamin

Bug in pdf/pdftables.w
by Lars Hamren 12 Sep '16

12 Sep '16

Hi, Those who enjoy such things can try to find the bug in this code, which happes to have for quite some time: int pdf_create_obj(PDF pdf, int t, int i) { int a; char *ss = NULL; if (pdf->obj_ptr == sup_obj_tab_size) overflow("indirect objects table size", (unsigned) pdf->obj_tab_size); if (pdf->obj_ptr == pdf->obj_tab_size) { a = pdf->obj_tab_size / 5; if (pdf->obj_tab_size < sup_obj_tab_size - a) pdf->obj_tab_size = pdf->obj_tab_size + a; else pdf->obj_tab_size = sup_obj_tab_size; pdf->obj_tab = xreallocarray(pdf->obj_tab, obj_entry, (unsigned) pdf->obj_tab_size); } pdf->obj_ptr++; obj_info(pdf, pdf->obj_ptr) = i; obj_type(pdf, pdf->obj_ptr) = t; It is both simple and potentially fatal. Answer in my next post. /Lars ------------------------------------------------------------------- Lars Hamrén WWW...: www.sdu.se Vadmöllan 211 Mobile: +46(705)189090 S-225 94 Lund Sweden
