On one of my x86_64-linux systems with GCC CVS from 20041231, the testcase uses
in a minute all available memory and therefore the process is killed.
This happens not only on x86_64 but also on ia64 and ppc - it seems to work
on i386.
On my other x86_64-linux system with GCC CVS from 20050101 the testcase uses
constant memory - but seems to be in an endless loop.
Note the compilers are not configured exactly the same.
Here's some information with the later system:
