R devel - Mar 2014 - Error: C stack usage is too close to the limit

Hi,

I have been using my own C++ plugin for a while.

On a new machine I now keep getting the

C stack usage is too close to the limit

error. I played with it and it appears to come after I printed a fixed
number of text to R via Rprintf (not from the main thread).

Didn't happen on the old machine. Old version was 2.14. Now on 3.0.3.

Not sure whats going on.

Did you read 'Writing R Extensions' about the support for threads?  E.g.

'Calling any of the R API from threaded code is ?for experts only?: they 
will need to read the source code to determine if it is thread-safe.  In 
particular, code which makes use of the stack-checking mechanism must 
not be called from threaded code.'

It reads like that is what you did.

I have similar experience previously. What I done was disabling stack limit
checking
    
    R_CStackLimit = -1;

and increasing the stack size to .16*1024*1024.

Hope it helps.
