Thank you both for your similar answers. I learned a lot by studying the mailing list archives and experimenting. After a lot of trials, I found the solution: On the 4 GB machine, I compiled the kernel with MAXDSIZ="(2048*1024*1024)" to achieve a max data segment size of 2 GB. This seems to cause the problems, maybe by a signed int overflow? Reducing MAXDSIZ helps.
