...D: By reading this post in Stackoverflow http://stackoverflow.com/questions/7458364/growing-an-r-matrix-inside-a-c-loop/7458516#7458516 I understood that it was necesary to (1) create the "child lists" and protecting them with PROTECT_WITH_INDEX, and (2) changing its size using SETLENGTH (Rf_lengthgets) and REPROTECT ing the lists in order to tell the GC that the vectors had change. THIRD: Once my two vectors are done ("id" and "lambda"), assign them to the i-th element of the "mother list" L1 using SET_VECTOR_ELT(VECTOR_ELT(L1,i), 0, duplicate(id)); SET_VECTOR...

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
