Comment (by martin):

 This error is caused by passing an empty string to synthetic as the first
 part of a string list. This happens because either the file read through
 std.fileread is non-existant, or the file is too large to fit in the
 workspace while dealing with the temporary header variable in the
 vcl_error code. (Note that the synthetic function is able to accept the
 result from std.fileread directly, making it unnecessary to pass it
 through a temp header. Using the temp header will also result in a large
 HTTP header being passed to the client, wasting bandwidth). Patch for this
 issue has been sent to the dev list awaiting review.
