Is it a pure Python implementation or has some C code too? Python got in 2.3 a heapq module in its standard library; I think it is what you want, no need for an additional module. > *** glibc detected *** free(): invalid pointer: 0x00002ad7b5720288 *** > Abort > > And on my PowerBook: > python2.5(8124) malloc: *** Deallocation of a pointer not malloced: > 0x3b4218; This could be a double free(), or free() called with the > middle of an allocated block; > > A memory fault can also be immediately triggered by apply 'del' to a > PQueue-instance.

Ah! then I bet: - There is some C code involved. - It carelessly mixes PyMem_Malloc with PyObject_Free or similar as described in http://docs.python.org/whatsnew/ports.html So do yourself a favor and forget about such old piece of code... -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
