[asterisk-dev] Memory leak when use ast_set_read_format

[MohammedShehzad]

Hi all,

My custom IVR application of asterisk records the voice of user.
It sets the read format to sleaner using ast_set_read_format funciton on
line number  2144.
        flag = ast_set_read_format(chan, AST_FORMAT_SLINEAR);
Which is leaving behind some leaks : below is the part of the trace of
asterisk under run valgrind as below:

==11972==
==11972== 52,512 bytes in 3 blocks are definitely lost in loss record 115 of

==11972==    by 0x376E4D3C2C: clone (in /lib64/libc-2.5.so)
==11972==

I do reset the read format back to old read format, but even though it is
showing leaks.

Any one can please let me know what i am missing in using
ast_set_read_format function?
