weird data corruption

[Frederik Eaton]

Hi,

I'm seeing some odd data corruption in a log file. Below, the second
line should be a SQL query (prefixed by a timestamp). It's turned into
garbage, but apparently not just random bytes. I'm using HSQL - that's
the only external library, and it uses FFI, so there might be some bad
memory management, but I thought I should ask if other people have
seen something similar. It's the second time this has happened to me.
