[gentoo-user] segfault from C stack overflow

When emerging R, I got:

...
** R
** data
*** moving datasets to lazyload DB
** demo
** inst
** byte-compile and prepare package for lazy loading
Error: segfault from C stack overflow
...

Since linux automatically grows the stack, doesn't this mean
that I'm out of memory.

Btw. 
# prlimit -s
RESOURCE DESCRIPTION       SOFT      HARD UNITS
STACK    max stack size 8388608 unlimited bytes

and prlimit --stack=-1:-1 doesn't change the soft limit.
