2020-06-15 Thread Marius Hillenbrand
Public bug reported: easystroke fails to build on s390x with -march=z13 and newer (as introduced in Ubuntu 20.04) because of an unexpected interaction of C++ template and compiler optimizations. tl;dr: The code relies on compiler- and optimization-level dependent behavior and the relatively

[Bug 1904899] [NEW] pixel color access delivers wrong data on s390x (e.g., tests/color_test.py)

2020-11-19 Thread Marius Hillenbrand
Public bug reported: When using an Imagemagick compiled with HDRI=1 (e.g., ,libmagickwand-6.q16hdri-6) many color-related test cases in wand fail. The root cause is that python-wand assumes that ImageMagick's QuantumType would be float for 16-bit HDRI. However, in that config QuantumType is

Indeed, my patch is just broken. I have not received any upstream feedback about the patch or the proposed alternatives -- unfortunately, clucene's community appears rather inactive, with 0 emails on the developer list in the last three months. -- You received this bug notification because you

fyi, fixed patch for clucene to keep the ABI constant on s390x is attached to https://sourceforge.net/p/clucene/bugs/233/. The patch requires that clucene uses a separate type clucene_float_t in its API, with multiple yet trivial changes all across the code base. None of the packages that depend
