Thanks, I will include your fix in the next snapshot release.
However, I'm still not sure this really an error in the dumplib.c source
rather than in gcc 4.4.1.
According to my reading of the snprintf man page, prefix is the format in
this case and the ordinary characters in that format, "0x", are merely
copied to the output stream:
... The format is composed of zero or more directives: ordinary
characters, which are simply copied to the output stream and
conversion specifications, each of which results in the fetching of
zero or more arguments.
