gDistance problem on RHEL 6 64-bit

Hello all, I am having a problem with rgeos::gDistance on RHEL 6. Everytime I try to get a point to point distance, I get R: GeometryComponentFilter.cpp:34: virtual void geos::geom::GeometryComponentFilter::filter_ro(const geos::geom::Geometry*): Assertion `0' failed. Aborted (core dumped) This only occurs on my RHEL 6 machine. Win 7 and Ubuntu 14.04 work fine.
The key question is how you installed rgeos and GEOS on these platforms. Most likely rgeos on Windows 7 is the CRAN binary statically linked to GEOS, and on RHEL6 and Ubuntu 14.04 rgeos is installed from source and links to the GEOS found on those platforms. We need the output of: version_GEOS() on each platform. Most likely you've not installed GEOS from source on either of the two Linux platforms. The cause is most likely a mismatch on the RHEL platform, possibly that GEOS has fallen behind C++, or that GEOS got updated without you re-installing rgeos. Is gDistance() the only function that doesn't work - can you run example(gDistance) and/or the examples of other functions? Roger
Some code to reproduce the problem: library(sp) library(rgeos) pt1<-SpatialPoints(data.frame(x=c(1,3),y=c(3,1))) pt2<-SpatialPoints(data.frame(x=1,y=1)) gDistance(pt2,pt1) More info:
