search for: allocbuffer

I was hit by ugly crashes of R, when I tried to read big data sets ("volcano"). So I looked into the code and found the following in character.c (triggered by substr()): I assume that the helper function AllocBuffer() shall facilitate an economic memory management. But the use of realloc() in the else-branch does not conform to ANSI and may hit you with certain compilers. When called with len<0 the code is assumed to re-size buff to MAXELTSIZE: realloc(buff, 0); buff = (char *) realloc(buff, MAXELTSIZ...
