Unfortunately, there is still lack of free sub-pixel rendering capable pdf viewer. Therefore some people like me have to stick with Adobe Reader. Uninstalling stix-fonts solves the sigfault problem for me. The strace log: open("/usr/share/fonts/stix-fonts/STIX2Math.otf", O_RDONLY) = 6 fcntl64(6, F_SETFD, FD_CLOEXEC) = 0 fstat64(6, {st_mode=S_IFREG|0644, st_size=755584, ...}) = 0 mmap2(NULL, 755584, PROT_READ, MAP_PRIVATE, 6, 0) = 0xf2c7a000 close(6) = 0 mmap2(NULL, 757760, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xf2bc1000 --- SIGSEGV {si_signo=SIGSEGV, si_code=SI_KERNEL, si_addr=NULL} --- rt_sigaction(SIGABRT, {sa_handler=SIG_DFL, sa_mask=[ABRT], sa_flags=SA_RESTART}, {sa_handler=0x850aafa, sa_mask=[], sa_flags=0}, 8) = 0 exit_group(1) = ? +++ exited with 1 +++
Thank you for the report, but the acrobat reader will be removed from the official gentoo tree soon. Perhaps someone will maintain it on an overlay: https://gpo.zugaina.org/app-text/acroread
