Re: segfault calling SSE enabled library from ctypes

Replying to myself: haypo found the origin of the problem. Apparently this problem stems from a GCC bug [1] (that should be fixed on x86 as of version 4.4). The bug is that GCC does not always ensure the stack to be 16 bytes aligned hence the "__m128 myvector" local variable in the previous code

Hi All, We've been debugging a distributed app that uses a database server to accept connections and then queries from remote agents. Once a connection is established it is passed off to a thread, along with a local db connection from a pool, to handle the IO. We get to a point that seems to be a
