python dumps core

[Thomas Klausner <wiz%NetBSD.org@localhost>]

After updating my userland from 20080427 to 20080428 from a few hours
ago, many programs just segfault.

Example:
# python2.4
Segmentation fault (core dumped)
# gdb python2.4 python2.4.core
...
(gdb) bt
#0  0x00007f7ffd907819 in pthread_curcpu_np () from /usr/lib/libpthread.so.0
#1  0x00007f7ffd291b02 in posix_memalign () from /usr/lib/libc.so.12
#2  0x00007f7ffd29229b in malloc () from /usr/lib/libc.so.12
#3  0x00007f7ffdba958b in PyInterpreterState_New () from 
/usr/pkg/lib/libpython2.4.so.1.0
#4  0x00007f7ffdbabb0e in Py_InitializeEx () from 
/usr/pkg/lib/libpython2.4.so.1.0
#5  0x00007f7ffdbb0b74 in Py_Main () from /usr/pkg/lib/libpython2.4.so.1.0
#6  0x000000000040089f in ___start ()
#7  0x00007f7ffdffa000 in ?? ()
#8  0x0000000000000001 in ?? ()
#9  0x00007f7ffffff6b8 in ?? ()
#10 0x0000000000000000 in ?? ()

mldonkey also segfaults.

Any ideas?
