[Rd] segfault on large number of open brackets (PR#7859)
Full_Name: Max
Version: R 2.0.1 (2004-11-15)
OS: Gentoo Linux
Submission from: (NULL) (158.143.49.181)
I leaned on the "(" key by accident, and it looks as if R segfaults on
a large
number (88 or more in my case) open brackets:

Yes, it is coincidence. I have found the error and have a fix: more detailed message to follow.

[Rd] segfault on large number of open brackets (PR#7859)
I suspect that is coincidence, as I can see no source change that would
account for it.
2.0.1 and R-devel work for me and 2.1.0 segfaults with
999 KeepSource = *LOGICAL(GetOption(install("keep.source"),
R_NilValue));
(gdb) bt
#0 0x080ca229 in ParseInit () at gram.y:999
#1 0x080cb305 in token () at gram.y:1530
I am not sure that is right, but I am pretty sure that
static char contextstack[50], *contextp;
just above is an unchecked nesting limit, as in
static void IfPush(void)
{
if (*contextp==LBRACE ||
*contextp=='[' ||
*contextp=='(' ||
*contextp == 'i')
*++contextp = 'i';
}
However, although I thought this was the problem, it seems only to apply
to nested if()s. So I do not currently have a solution.
