...long) n; mI = (double*) R_alloc(vs, sizeof(double)); I suspect this caused by allocString(int), which is called by R_alloc, see below. Would it be possible to have allocString take a long argument as well?

...want to write a little stand-alone C program that calls R_alloc, but I get a segmentation fault: int main(int argc, char** argv){ double* d = (double *)R_alloc(2, sizeof(double)); // <- segmentation fault! return 0; } gdb reveals that sizeof(double) evaluated to 0: > R_alloc (nelem=2, eltsize=0) at memory.c:1649 so it results in the segfault later. This is how I compile my program: $ cd R-2.6.1/src/main $ gcc -std=gnu99 -I../../src/extra/zlib -I../../src/extra/bzip2 -I../../src/extra/pcre -I. -I../../src/include -I../../src/include -I/usr/local/include -DHAVE_CONFIG_H -g -c main.c...

The current version of S_alloc in src/main/memory.c is char *S_alloc(long nelem, int eltsize) { unsigned int i, size; char *p = R_alloc(nelem, eltsize); for(i=0 ; i<size; i++) p[i] = 0; return p; } which segfaults because `size' is not initialized. I am not what the right fix is, adding size = nelem * eltsize; before the loop seems to work. As an aside ... I think the se...

Hi everyone! I think I stumbled over a bug in the latest R 2.9.2 patched for OS X: > R version 2.9.2 Patched (2009-09-24 r49861) > i386-apple-darwin9.8.0 When I try to sort latin1-encoded character vectors, R sometimes crashes with a segmentation fault. I'm running OS X 10.5.8 and have observed this behaviour both with the i386 and x86_64 builds, in the R.app GUI as well as on
