I would check the version of libreadline you compiled against. Tab
completion involves that library.
It works correctly for all my local builds, and nothing in that area in
the R sources has changed for a long time. I believe I am using
http://r.research.att.com/libs/readline-5.2-12-darwin8-bin4.tar.gz .
And this is on Lion whereas Simon is building on Leopard (AFAIK).

I've just built R-devel (r60889) from source on my Mac OS X 10.6.8

Still, I seem to pass "make check" and
"make test-Segfault" in the tests directory with no problem, but the
following leads
to a persistent error + instant abort.
1) Start R
2) Type "tools::"
3) Tab to attempt to auto-complete
resulting in some variation on
mweylandt-laptop:~ michaelweylandt$ rDEVEL/bin/R --vanilla -q
tools::R(44436) malloc: *** error for object 0x1006d8700: incorrect checksum
for freed object - object was probably modified after being freed.
*** set a breakpoint in malloc_error_break to debug
Abort trap
at which point hitting <RET> drops me back into bash. This seems to
only occur with tools and no other packages (that I've found). It also
occurs whether tools has been library()'d or not, but sometimes it
takes two tabbings.
My compiler info follows
mweylandt-laptop:~ michaelweylandt$ gcc --version
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)

mweylandt-laptop:~ michaelweylandt$ gfortran --version
GNU Fortran (GCC) 4.2.1 (Apple Inc. build 5664)

I do think that it's only a problem with my local build, as I can't
replicate with Simon's nightly builds (http://r.research.att.com/),
which are at r60887 currently. Is there anything else I should check
with my setup? I don't see any advice on this particular issue in the
R installation manual, but I easily could have overlooked it.
Thanks,
Michael
