[Bug libgcj/22341] New: Interix: gcj out of virtual mem during libgcj make

[klaus dot kusche at inode dot at]

When making libgcj on Interix, make reproducibly fails in those steps where 
many class files are compiled into a single object, e.g. when making gnu-xml.o.

The error given by gcj is "virtual memory exhausted: Permission denied".
Watching "gcj" in the task manager confirms this: It has about 1.5 GB virt mem 
just before the error.

Changing "GCJFLAGS" from "-O2" to "-O" in "Makefile" works around the problem.

I want to say this is not really a GCC bug.

But on supported configurations (and afaik interix is one of them), an out-of-
the-box gcc build (incl. libgcj) should not be guranteed to fail.

This is no physical limit (memory size, swap space, ...), we tried on several 
different systems, all failed in the same way.

It is a fundamental architectural problem: There is a 2 GB virtual address 
space limit for each process in Windows, and in combination with the way 
windows loads DLLs etc., gcc will hit this limit when building libgcj with the 
default settings, no matter how large the hardware is.

You need more memory.  While the target may be supported, it might not be
supported as a host.
