I've been noticing a few (4 in the last week) crashes with my Python
servers since I updated to PyLucene 2.0.0. Always in the PyLucene
thread. This is with Python 2.3.5 on Mac OS X 10.4.6, using gcj 3.4.4.
The thread that crashes is doing a search (though I'm not sure just
*what* search).
I've enclosed a sample crash dump. They all have the form (in the
thread where the crash occurs):
Exception: EXC_BAD_ACCESS (0x0001)
Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000000
