I've just built R-devel (r60889) from source on my Mac OS X 10.6.8 using gcc from Xcode and gfortran from Simon. I didn't use all the recommended configuration flags only
./configure && make 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) Copyright (C) 2007 Free Software Foundation, Inc. mweylandt-laptop:~ michaelweylandt$ gfortran --version GNU Fortran (GCC) 4.2.1 (Apple Inc. build 5664) Copyright (C) 2007 Free Software Foundation, Inc. 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.
