Created attachment 709779 [details] emerge --info output Library opensc-pkcs11.so, contained in package opensc, segfaults when used on ~amd64 system. (As common browsers, mail clients and so on use it, when it's installed, it also prevent running these applications). Steps to reproduce: - install opensc - run pkcs11-tool -t In my case, running command return this: spm-ntb /home/spm # pkcs11-tool -t Neoprávněný přístup do paměti (SIGSEGV) and in dmesg I can notice this: [59239.001156] pkcs11-tool[10853]: segfault at 48 ip 00007f662fcf35e6 sp 00007fffa24f3440 error 6 in opensc-pkcs11.so[7f662fce0000+1d000]

Created attachment 710067 [details] build.log
Can't reproduce and build log is not helpful for sure. Please provide gdb strace.
Ok, could you advice to gdb virgin what to do with it? :-) I have successfully run command and got backtrace, but I'm not sure if it's what you want. Backtrace below... (gdb) run -t The program being debugged has been started already. Start it from the beginning? (y or n) y Starting program: /usr/bin/pkcs11-tool -t [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib64/libthread_db.so.1".

I also had 100% reproducible segfaults in opensc-pkcs11.so and onepin-opensc-pkcs11.so when dev-libs/opensc-0.21.0-r1 was built with gcc-11. That prevented running firefox and evolution. Had no such problem with gcc-10. Updating to dev-libs/opensc-0.22.0 fixed this issue as well.
