[Rd] AIX testers needed

Per the request to test the latest tarball referenced below, I have
built R on AIX 5.3. There is a memory issue, please see 3) below.
1) Build with --enable-BLAS-shlib option. Builds and
passes "make check".
2) GNU libiconv was installed; R configured *without*
iconv option. Builds and passes "make check."
3) Memory issue:
a) Although the server possesses 8GB of RAM and
system("ulimit") returns "unlimited" as its value, R does not
"have enough memory."
b) This code works on R-2.4.0 on WinXP with 2GB of RAM, but
fails on the AIX build. Example code:
> xx <- matrix(rep(1e+10,1e7),nrow=1e4,ncol=1e3)
> tmp.df <- as.data.frame(cbind(xx,xx,xx))
Error: cannot allocate vector of size 228.9 Mb
used (Mb) gc trigger (Mb) max used (Mb)
Ncells 233035 6.3 467875 12.5 350000 9.4
Vcells 10104141 77.1 31854441 243.1 30104289 229.7
4) Used gcc-4.1.2; I have not tried the native compiler.
1) Are there suggestions on how to diagnose and resolve the memory
issue? I'm still building my tool chain and I am in the midst of
2) Regarding the build process itself, is there more documentation
or results that I should forward?
