Control: tags -1 pending Hi David,
Following up on parsinsert failing to build from source on POWER 64 bits little endian on Debian Testing, I found out that reducing the compiler optimization level to -O1 allows the test suite to pass. The affected configuration is Debian 11 at Testing stage, with Gcc 10.2. Affected CPU architectures are armel, armhf, mips64el, ppc64el (which is the subject of Debian Bug#976929[1]) and riscv64. Normally, the package is built for Debian with optimization level -O2, and this passes for all other architectures, including but not limited to amd64, arm64, i386, mipsel, and s390x. Interestingly, when pushing to -O3, the problem may appear on amd64 architecture, see #964082[2], but it does not seem to be reproducible on every amd64 CPU though. In any case, the erroneous results in output are the same as on more exotic architectures. [1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=976929 [2] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=964082 I also gave a shot to -Os, sitting in between -O1 and -O2, and most interestingly, I had a rather different output: [...] Loading sequence 180000 Loading sequence 200000 Loading sequence 220000 taxomony index file: 224931 taxa Reading Newick Tree: [core_rdp.ntree] opening source file: [core_rdp.ntree] Opening file: core_rdp.ntree ...Parsing Newick file: core_rdp.ntree ...Processed 246406 chars of 246447 Newick Tree Read Completed: 10143 taxa, 0 sec Found duplicate name: [W<85><9c>Ý<9c>U]/nFound duplicate name: [W<85><9c>Ý<9c>U]/n...

Not sure how relevant this is though.
