Malloc assert violation with glibc-2.13

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compile ana-net with app examples
2. Run any server app that use ana-net in this case: 'chat'

What is the expected output? What do you see instead?
The chat server must started with the following message: "Server running, Enter 
to quit."

But instead appear this error:
server: malloc.c:3096: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) 
&((av)->bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) 
&& old_size == 0) || ((unsigned long) (old_size) >= (unsigned 
long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * 
(sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)->size & 
0x1) && ((unsigned long)old_end & pagemask) == 0)' failed.
Aborted

What version of the product are you using? On what operating system?
Ubuntu 11.04
glibc-2.13
g++ 4.5.2
