I work with the Sage project, and we are trying to improve the ability

This discussion might be more appropriate for R-devel. I'm not all that
familiar with the Sage project and it isn't clear to me whether what you
are seeing is in any way Sage-specific.
If you are getting this segfault from a basic configure/make/make check
sequence and you can reproduce the crash, then further debugging steps
will likely be of interest.
R builds just fine on both Mac and Linux, but some things in make
check seem to break on certain Linux boxes that don't on Mac or other
machines. Here is an example from (Red Hat?) in doing the basic
tests, in src/tests/Examples/, where base-Ex.R seems to have a
problem, at the end of base-Ex.Rout.fail:
### Name: groupGeneric
### Title: S3 Group Generic Functions
### Aliases: S3groupGeneric .Group Math Math.data.frame Ops Ops.data.frame
### Summary Summary.data.frame Complex 'group generic'
### Keywords: methods
### ** Examples
require(utils)
d.fr<- data.frame(x=1:9, y=stats::rnorm(9))
class(1 + d.fr) == "data.frame" ##-- add to d.f. ...
[1] TRUE
methods("Math")
*** caught segfault ***
address 0x4b8, cause 'memory not mapped'
You might be able to reproduce this and get some more information like this:
R -d gdb
run
source("src/tests/Examples/base-Ex.R")
Assuming you get a crash, type bt in the gdb console and send output.
