Hi John, I am using Debian on RaspberryPi and everything is from the official apt package manager.
Hardware architecture: armv7l GNU/Linux OS version: Raspbian GNU/Linux 11 (bullseye) Libmicrohttpd: stable, 0.9.72-2 armhf Valgrind: valgrind-3.7.0 I can also share the code that I was testing: https://github.com/alex-lt-kong/public-address-client Exact invocation and surrounding output: # valgrind --leak-check=yes --log-file=/tmp/valgrind.rpt $HOME/bin/public-address-client/pac.out Error accepting connection: Function not implemented Error accepting connection: Function not implemented Error accepting connection: Function not implemented Error accepting connection: Function not implemented Error accepting connection: Function not implemented Error accepting connection: Function not implemented Error accepting connection: Function not implemented Error accepting connection: Function not implemented Error accepting connection: Function not implemented Error accepting connection: Function not implemented [a lot more identical rows...] strace output: 3454 cacheflush(0x42714b70, 0x42714ca0, 0) = 0 3454 cacheflush(0x42714ca0, 0x42714d20, 0) = 0 3454 cacheflush(0x42714d20, 0x42714dec, 0) = 0 3454 cacheflush(0x42714df0, 0x42714f28, 0) = 0 3454 cacheflush(0x42714f28, 0x427150e0, 0) = 0 3454 getpid() = 3454 3454 write(1026, "==3454== \n", 10) = 10 3454 getpid() = 3454 3454 getpid() = 3454 3454 getpid() = 3454 3454 getpid() = 3454 3454 write(1026, "==3454== HEAP SUMMARY:\n==3454== "..., 170) = 170 3454 rt_sigprocmask(SIG_SETMASK, NULL, ~[ILL TRAP BUS FPE KILL SEGV STOP], 8) = 0 3454 rt_sigprocmask(SIG_SETMASK, ~[ILL TRAP BUS FPE KILL SEGV STOP], NULL, 8) = 0 3454 rt_sigprocmask(SIG_SETMASK, NULL, ~[ILL TRAP BUS FPE KILL SEGV STOP], 8) = 0 3454 rt_sigprocmask(SIG_SETMASK, ~[ILL TRAP BUS FPE KILL SEGV STOP], NULL, 8) = 0 3454 rt_sigprocmask(SIG_SETMASK, NULL, ~[ILL TRAP BUS FPE KILL SEGV STOP], 8) = 0 3454 rt_sigprocmask(SIG_SETMASK, ~[ILL TRAP BUS FPE KILL SEGV STOP], NULL, 8) = 0 [The last row repeats a lot of times] I am not very sure on how to count twenty syscalls since the beginning of the error though. Please let me know if you notice any issues. I will leave the mail for a while then I will file a report to bugs.kde.org.
