Hi All, Well I finally have found the time to get svn working and I have successfully built my own tuned atlas (multi-threaded version) libs and have both the r-devel and r-patched trees building daily on my box. The problem is I still do not have a good idea of the layout and design of R, and typically I "learn by doing" by trying to fix a bug that hits me. Unfortunately ;-)

Dear all, It seems that textConnection() can trigger a segmentation fault. The following script (using two large loops) makes this bug reproducible: for (i in 1:10000) { z=textConnection(NULL,open='w') for (j in 1:100) { write(runif(1)*1e6,file=z) write('\n',file=z) } close(z) } The bug could be reproduced on R-2.6.1, R-2.7.0 and on the latest R-devel
