Python 2.5 tightens the requirements that memory allocated via one memory management API family must be released via calls through the same API family - eg malloc() -> free(); PyMem_Malloc() -> PyMem_Free(); PyObject_Malloc() -> PyObject_Free(). I think I recall something about this in one of the "whats new" type docs. A fair bit of code erroneously assumes that free() can be used to release any block of memory, regardless of which API family was used to allocate the memory. This code needs to be fixed. -- - Andrew I MacIntyre "These thoughts are mine alone..."

Steve, I recompiled the library for the 2.5 version. If it makes a difference, I used the altinstall option for python, so it's installed as python2.5.

Compiled extensions are specific to a particular major version of Python, so (for example) 2.3 extension modules won't run under 2.4.

_mssql on Python 2.5 Beta 2
I'm trying to use the _mssql module from http://pymssql.sourceforge.net/. It works fine on Python 2.4. I've just installed Python 2.5 Beta 2 on my Linux box and, whenever I try and run the mssql.close() function, or close the program, I get the following message: *** glibc detected *** python2.5: free(): invalid pointer: 0xb7f08320 *** === Backtrace: = /lib/libc.so.6[0xa68424] /lib/libc.so.6(__libc_free+0x77)[0xa6895f] /usr/local/lib/python2.5/site-packages/_mssql.so[0x7f5d8c] python2.5[0x8080a72] python2.5(PyDict_SetItem+0x6c)[0x8080e4c] python2.5(_PyModule_Clear+0x15d)[0x8083929] python2.5(PyImport_Cleanup+0x1e5)[0x80d1159] python2.5(Py_Finalize+0xaf)[0x80dc4c3] python2.5(Py_Main+0x39d)[0x805646d] /lib/libc.so.6(__libc_start_main+0xc6)[0xa19de6] python2.5[0x8055f89] === Memory map: 00131000-00175000 r-xp 03:03 6723934 /usr/lib/libncursesw.so.5.4 00175000-0017d000 rwxp 00044000 03:03 6723934 /usr/lib/libncursesw.so.5.4 0017d000-0017e000 rwxp 0017d000 00:00 0 001fa000-0023f000 r-xp 03:03 166172 /usr/local/lib/libsybdb.so.5.0.0 0023f000-00242000 rwxp 00045000 03:03 166172 /usr/local/lib/libsybdb.so.5.0.0 004b7000-004c r-xp 03:03 4124789 /lib/libnss_files-2.3.5.so 004c-004c1000 r-xp 8000 03:03 4124789 /lib/libnss_files-2.3.5.so 004c1000-004c2000 rwxp 9000 03:03 4124789 /lib/libnss_files-2.3.5.so 0074c000-0075a000 r-xp 03:03 4124807 /lib/libpthread-2.3.5.so 0075a000-0075b000 r-xp d000 03:03 4124807 /lib/libpthread-2.3.5.so 0075b000-0075c000 rwxp e000 03:03 4124807 /lib/libpthread-2.3.5.so 0075c000-0075e000 rwxp 0075c000 00:00 0 0076f000-00778000 r-xp 03:03 4127052 /lib/libgcc_s-4.0.2-20051126.so.1 00778000-00779000 rwxp 9000 03:03 4127052 /lib/libgcc_s-4.0.2-20051126.so.1 007dc000-007dd000 r-xp 007dc000 00:00 0 007f4000-007f8000 r-xp 03:03 2324725 /usr/local/lib/python2.5/site-packages/_mssql.so 007f8000-007f9000 rwxp 4000 03:03 2324725 /usr/local/lib/python2.5/site-packages/_mssql.so 007f9000-007fb000 rwxp 007f9000 00:00 0 008b8000-008ba000 r-xp 03:03 4127074/lib/libutil-2.3.5.so 008ba000-008bb000 r-xp 1000 03:03 4127074/lib/libutil-2.3.5.so 008bb000-008bc000 rwxp 2000 03:03 4127074/lib/libutil-2.3.5.so 009e7000-00a01000 r-xp 03:03 4127066/lib/ld-2.3.5.so 00a01000-00a02000 r-xp 00019000 03:03 4127066/lib/ld-2.3.5.so 00a02000-00a03000 rwxp 0001a000 03:03 4127066/lib/ld-2.3.5.so 00a05000-00b29000 r-xp 03:03 4127067/lib/libc-2.3.5.so 00b29000-00b2b000 r-xp 00124000 03:03 4127067/lib/libc-2.3.5.so 00b2b000-00b2d000 rwxp 00126000 03:03 4127067/lib/libc-2.3.5.so 00b2d000-00b2f000 rwxp 00b2d000 00:00 0 00b31000-00b33000 r-xp 03:03 4127069/lib/libdl-2.3.5.so 00b33000-00b34000 r-xp 1000 03:03 4127069/lib/libdl-2.3.5.so 00b34000-00b35000 rwxp 2000 03:03 4127069/lib/libdl-2.3.5.so 00b37000-00b59000 r-xp 03:03 4127073/lib/libm-2.3.5.so 00b59000-00b5a000 r-xp 00021000 03:03 4127073/lib/libm-2.3.5.so 00b5a000-00b5b000 rwxp 00022000 03:03 4127073/lib/libm-2.3.5.so 00b86000-00b95000 r-xp 03:03 4124849 /lib/libresolv-2.3.5.so 00b95000-00b96000 r-xp e000 03:03 4124849 /lib/libresolv-2.3.5.so 00b96000-00b97000 rwxp f000 03:03 4124849 /lib/libresolv-2.3.5.so 00b97000-00b99000 rwxp 00b97000 00:00 0 00b9b000-00bc2000 r-xp 03:03 4190263 /usr/lib/libreadline.so.5.0 00bc2000-00bc6000 rwxp 00027000 03:03 4190263 /usr/lib/libreadline.so.5.0 00bc6000-00bc7000 rwxp 00bc6000 00:00 0 00c0-00c01000 r-xp 03:03 6715661 /usr/lib/gconv/ISO8859-1.so 00c01000-00c03000 rwxp 03:03 6715661 /usr/lib/gconv/ISO8859-1.so 00c43000-00c46000 r-xp 03:03 1178681 /usr/local/lib/python2.5/lib-dynload/time.so 00c46000-00c48000 rwxp 2000 03:03 1178681 /usr/local/lib/python2.5/lib-dynload/time.so 00c8d000-00c91000 r-xp 03:03 1178665 /usr/local/lib/python2.5/lib-dynload/collections.so 00c91000-00c92000 rwxp 4000 03:03 1178665 /usr/local/lib/python2.5/lib-dynload/collections.so 00d89000-00d97000 r-xp 03:03 1178660 /usr/local/lib/python2.5/lib-dynload/datetime.so 00d97000-00d9a000Aborted Any suggestions?
