--- Begin Message ---Package: fetchmail Version: 6.4.16-4 Severity: important -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear Maintainer, fetchmail started SEGFAULTing after upgrading from buster to bullseye. This is an example config which causes this: test@canardo:~$ cat .fetchmailrc set invisible defaults proto pop3 uidl no envelope poll pop.example.com user foo with pass bar is test here Note that the example can be uses as-is. The server and user does not need to exist. fetchmail crashes on parsing before trying to lookup servername or anything: test@canardo:~$ strace -f fetchmail 2>&1|tail -10 openat(AT_FDCWD, "/home/test/.fetchmailrc", O_RDONLY) = 3 ioctl(3, TCGETS, 0x7ffdf5799df0) = -1 ENOTTY (Inappropriate ioctl for device) fstat(3, {st_mode=S_IFREG|0600, st_size=116, ...}) = 0 read(3, "set invisible\ndefaults\n proto p"..., 8192) = 116 read(3, "", 4096) = 0 read(3, "", 8192) = 0 ioctl(3, TCGETS, 0x7ffdf5799df0) = -1 ENOTTY (Inappropriate ioctl for device) close(3) = 0 - --- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=0xffffffffffffffe0} --- +++ killed by SIGSEGV +++ Moving the settings from "defaults" to the server section works around the issue.
