This change does not help ```diff struct bencode_item { + bencode_buffer_t *buffer; bencode_item_t *parent, *child, *last_child, *sibling; bencode_type_t type; struct iovec iov[2]; /* when decoding, iov[1] contains the contents of a string object */ unsigned int iov_cnt; unsigned int str_len; /* length of the whole ENCODED object. NOT the length of a byte string */ long long int value; /* when decoding an integer, contains the value; otherwise used internally */ - bencode_buffer_t *buffer; char __buf[0]; }; ```
The structure in master branch is:
```c struct bencode_item { bencode_type_t type; struct iovec iov[2]; /* when decoding, iov[1] contains the contents of a string object */ unsigned int iov_cnt; unsigned int str_len; /* length of the whole ENCODED object. NOT the length of a byte string */ long long int value; /* when decoding an integer, contains the value; otherwise used internally */ bencode_item_t *parent, *child, *last_child, *sibling; bencode_buffer_t *buffer; char __buf[0]; }; ```
Did you shift the other fields as well, not only the one in the diff?
yes, tried to do this but no luck.
From my point of view, RTPengine uses its own memory malloc function and this function does not align memory segments.
Closing it, being long time with no activity. If anyone wants to go on with it, can just make a PR.
Closed #3058 as completed.

Yes, almost certainly exactly the same issue
yes, I have compiled Kamailio sources with the fix and the issue was resolved.
