-------------------------------------------------------------------------

Realloc can't be fail. its strange. Server have more than 32 gb free memory and all compiled by x64. Maybe wrong address or anything other?

We have many calls in test. Maybe some calls after memory corruption do realloc fail, but valgrind simple say - payload was 512 bytes (init size of adress) and now 0 bytes. You was realloc it to 0 bytes becouse payload_len = 0 and you do realloc(...,0)...

I thnik its two different questions. First - why chan_sip do next work and second - why allocated buffer 512 of bytes stay 0 bytes (may be its normal and valgrind do panic) :)
