------- Comment #13 from pluto at agmk dot net 2006-08-10 09:58 -------
in fact it was a gcc bug.
gcc version 4.1.2 20060530 gives wrong code.
gcc version 4.1.2 20060712 gives correct code.
tree dump shows that gcc-20060530 removes some parts [*] of vector_base
initialization and finally crash during freeing invalid pointer.
