Install debuginfo packages for icecast and glibc, and configure abrt daemon.
When icecast crashes again, you can obtain a coredump from an abrt cache and
use GDB (or abrt tools) for obtaining a stack trace and exact line numbers
of icecast sources where the crash happened.

Alternatively you can retrieve the coredumps from system journal.
