I'm getting a bit further with bug 14267:
On OSX I am NOT seeing it with R-devel, although it is there with 2.11.0
Patched.
Running with a non-optimized compile, I can get some more information
It is happening on the i-th iteration of the loop in do_formatPOSIXlt with
(gdb) p i
$4 = 86870
Unfortunately, it looks like a bigger exercise to get valgrind running on Snow
Leopard -- too big for Friday afternoon anyway. However, the alloca() call on
line 774 of src/main/datetime.c does look suspect to me. I can see that it was
introduced with r51353 and has since disappeared in R-devel (r51398).
I've just committed a patch for this on R-2-11-branch. The problem was
that the alloca() was within a loop, so it kept allocating more and more
space until the end of the function call, and blew the stack. In
R-devel, this was changed to the C99 construct of defining a variable
sized array within a block, and that was fine, because it was released
at the end of the block, not at the end of the function call.
