I do not understand what you mean with "type of ext_sendmsg ... changed". The
parameters and its types have never changed; they are still
size_t ext_sendmsg(int s, const struct msghdr* msg, int flags); and
ssize_t ext_recvmsg(int s, struct msghdr* msg, int flags);

Do you have your program compiled with "-O0 -g"? If not, recompile and try
again. Also make sure that core files are generated ("ulimit -c unlimited").
Then, start "gdb" and load program and core file. Send us the stack trace
("bt" command). This will help to locate where the problem is.

If you run under Linux, also install the memory Debugger Valgrind
(http://developer.kde.org/~sewardj/). Execute your programs with "valgrind
<Your program> <Your parameters>". Valgrind will look for things like access
to uninitialized variables and freed memory, memory leaks etc..
