[root@ec2mail001 mail]# /usr/libexec/courier-authlib/authdaemond INFO: modules="authmysql", daemons=5 INFO: Installing libauthmysql Floating point exception

I did an strace here and found this:

open("/usr/lib/libidn.so.11", O_RDONLY) = 5 read(5, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\3\0\3\0\1\0\0\0\0M,H4\0"..., 512) = 512 fstat64(5, {st_mode=S_IFREG|0755, st_size=193764, ...}) = 0 old_mmap(0x482c3000, 195264, PROT_READ|PROT_EXEC, MAP_PRIVATE|MAP_DENYWRITE, 5, 0) = 0xb7e10000 old_mmap(0xb7e3e000, 8192, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_FIXED|MAP_DENYWRITE, 5, 0x2d000) = 0xb7e3e000 close(5) = 0 --- SIGFPE (Floating point exception) @ 0 (0) ---

Any ideas? This was installed via an RPM that was built directly on the EC2 server.

Courier does not link against libidn directly. This must be an indirect link via MySQL's libraries. Try running the mysql command line utility to see if you get the same segfault.
