[Freeswitch-dev] switch_ivr_originate.c(2621) uninitialized local variable 'b_frame'

I am having trouble to build FreeSwitch due to the following error: c:\dev\voip\freeswitch\src\switch_ivr_originate.c(2621): warning C4701: potentially uninitialized local variable 'b_frame' used c:\dev\voip\freeswitch\src\switch_ivr_originate.c(2621): error C2220: warning treated as error - no 'object' file generated I am using Visual Studio 2008. I could disable "warning treated as error" to continue compiling. But, I don't know this warning would ultimately cause any trouble later. I am raising this problem for other developers' attention on "potentially uninitialized variable".
