https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256205 --- Comment #2 from Robert Clausecker <fuz@fuz.su> --- We found that on our arm64 box, the following steps somewhat consistently produce a file afflicted with the issue: 1. on an arm64 FreeBSD 13.0 box, create an ARMv7 jail on a ZFS dataset 2. in that jail, download and unpack https://sourceforge.net/projects/schilytools/files/schily-2021-05-19.tar.bz2 3. enter schily-2021-05-19 and type "make" to compile 4. the file schily-2021-05-19/ved/OBJ/aarch64-freebsd-clang/ved then exhibits this problem The problem can then be reproduced by typing star/OBJ/armv7-freebsd-clang/star -c -sparse -v -f /dev/null ved/OBJ/armv7-freebsd-clang/ved with the observed output 'ved/OBJ/armv7-freebsd-clang/ved' is sparse a ved/OBJ/armv7-freebsd-clang/ved 226708 bytes, 1 tape blocks star: 1 blocks + 0 bytes (total of 10240 bytes = 10.00k). -- You are receiving this mail because: You are the assignee for the bug.
