[Rcpp-devel] R Memory Management and RInside

[gershon bialer]

Hi,

I figured out the bug. I'm on the mac, and I had recompiled R and my
application with GCC, but I had still had a bunch of libraries, which
had been built in LLVM. I suppose the issue with LLVM relates to how
it does memory management.

Thanks
