Problem: FreeSwitch crashes when called party hangs up on prompt played (prompt played on called side). Interestingly enough, this does not happen in DEV (win32 Windows 2003 VMs) but happens on win32 Windows 2003 HW (real hardware). Offending lib is libapr.dll. I ran libapr.dl through Dependency Walker on both VM and HW and all is equal.
