Hi yet again,

This seems relevant in the valgrind output, I get many of them before enough damage is done to corrupt the freelist:

And then the next 14 bytes are accessed illegally one by one up to 0x468a320f.
And then a similar sequence of consecutive bytes from 0x468a3600 to 0x468a360f until we crash:
