This is more likely the problem:

(gdb) p *o
$7 = {next = 0x0, name = 0x14ce0 "gtype-desc.h", buflength = 0, bufused = 0,
  buf = 0x0}

I tried the modification suggested by Paolo but had similar to Steve.
There's still an issue with extending the buffer (i.e., I get more
output if I initially make the buffer bigger).  However, there's still
junk at the end.

This has been fixed for me with this patch:

2007-03-29  Zack Weinberg  <zack@mrtock.ucsd.edu>

        * gengtype.c (oprintf): Mostly revert changes from 2007-03-26;
        add comment explaining why vsnprintf cannot be used.

Thanks for the pointer.  I'll update and close the PR if the problem
is fixed.
