Start in lib/requestHandler.js at the paths shown near lines 88, 145, and 179, then review the two stack traces separately. Reproduce or characterize the failures on the reported Windows 7 32-bit setup, focusing on the buffer concatenation and remote-response request paths. Done means the intermittent exceptions are understood and AnyProxy no longer exits unexpectedly in those cases.
