I am able to reproduce this. I'm using GCC 2.6.3 -O2, under Linux
1.2.0 on an Intel i486DX/33.
I'm running the program in an 80x15 xterm (note the small number of
lines), with the following TERMCAP:

Bill Mitchell reports that he gets the bug on a Linux console too, but
I can't reproduce it there. This may have something to do with the
fact that my console is 132x43.
I have patched the Info program very slightly, to correct a few minor
deficiencies. The patches are attached. Two of them are fixes for
bugs which have already been reported here; the other adds some
support needed for Debian's modular packaging scheme, where any
combination of Info and/or Emacs may be installed on a system.
When replying to this bug report, I'd be grateful if you'd preserve
the CC to debian-bugs@pixar.com, and keep the subject line starting
with `Re: Bug#627'. This will allow our automatic bug tracking system
to file your messages alongside the original report from Bill
Mitchell.
Ian.

I can reproduce this. I have to make the xterm I'm testing the
program in very small to get C-h not to split the window.
However, when I compile the program with -g -O2 and don't strip the
binary I'm unable to debug it because abort() has corrupted the stack
(why does abort ALWAYS have to corrupt the stack ?!).
If I take the -O flag off the compilation lines the bug goes away
(plain -O still triggers it).
I suspect a compiler (or perhaps library) problem. I'm using GCC
2.5.8 and libc 4.5.26.
Could someone with GCC 2.6.3 and a newer libc try it, please ?
Ian.
