> Upgraded a stable running system with t.38 support. Used latest version when compiling (13.27.0) and found outbound fax calls randomly segfault the system. Tried compiling earlier version and found the same issue repeatedly. Finally found 13.21.1 is stable in same environment. Backtrace supplied from core dump in 13.27.0.
