Then at least we can get a stack trace and a clue about where it is looping. Diddling optimization options can also sometimes provide a clue.
(Missed this earlier as the conversation moved off-list.)
And to keep the list abreast, this appears to be related to the long double
issue on powerpc where needed an extra #define to ensure compilation. That
commit is the difference in a bisection as I was able to demonstrate. The
issue can also be circumvented by disabling long double support on the
platform, but hopefully a better fix can be found. Bryan Lewis was
eagle-eyed on this and very helpful. The issue is now back in the hands of R
Core and I and others will await the news.
