Philipp,
this is probably the bug that I fixed last night. It is present in all 3.23,
4.0 and 4.1 versions.

mem0pool.c:
Fix a memory corruption bug: in 32-bit computers, every 4 billionth
malloc
outside innodb_additional_mem_pool_size was mistreated when freeing the
memory;
this could corrupt the InnoDB additional mem pool and could have caused
crashes
anywhere, also inside MySQL, or even database corruption! the bug exists
also in
3.23 and 4.1; workaround: configure innodb_additional_mem_pool_size big
enough
"
