| (I need this fixed before 2.3.3 since it is critical to something at work. I therefore promise to do it myself.) I tracked down a segfault on Windows (XP) in some windows registry traversal code I wrote. It uses _winreg.c, the crash is in PyEnumValue. I I think the cause is that the requested value was very large (several 100 KB) and the code does an alloca() for that much. I'm guessing this overflows the stack. The code needs to be rewritten to avoid alloca() I fear... | ||

| Logged In: YES user_id=6380 I've fixed this in 2.4 and 2.3. (I still need to do a test with a truly large registry value, but the only machine where I can reproduce this is not in my possession, so it may take a while). |
