Thank you - I attempted to use Rprintf as suggested. I also attempted
fprintf() using stdout. The platform is Linux
2.6.27.30-170.2.82.fc10.x86_64. It's a Fedora Core v10. I encountered
the same issue with both R v. 2.9.2 and 2.10.0 (currently running the
latter). If it helps, the following is the memcheck output after
making the suggested changes:
==25809== Invalid read of size 1
==25809== at 0x4D04209: SET_SYMVALUE (in /usr/lib64/R/lib/libR.so)
