Thanks for the info. Debian on USII works just fine, so, the problem
is likely in Linux kernel on USIII (or Debian kernel on USIII). I
don't think that it's connected with glibc or gcc version because it
crashed on glibc2.5-2.7 and gcc 4.1-4.3.

It's true, though there's only one sparc-specific patch (it removes
some optimization whish caused crashes in the past, when Erlang was
supposed to be built on 32-bit Sparcs too).
