xmalloccannot allocate 8bytes/Can't dlopen libc: outofmemory

[as.gentoo]

Hi,
I rented a vServer w/ maximum 512MB & min 256MB RAM. For a while I was able to compile what I wanted to. Whatever I try to emerge now - with exception of portage - I get libsandbox: Can't dlopen libc: out of memory. Shouldn't be 512MB enough to emerge grep or wget?

When emerging worked I emerged ccache, but I disabled it in make.conf in order to fix the problem - as well I set MAKEOPTS="-j1" but both did not help!

#FEATURES ="ccache stricter test"
FEATURES ="stricter test"
#CCACHE_SIZE ="2G"
#CCACHE_DIR ="/var/tmp/ccache"

I switched from a "normal" profile to hardened. Is it possible that PIE/PIC causes trouble if the memory is too low?

There is nothing special running jet:

Please help!

try taking -pipe out of your CFLAGS and CXXFLAGS

will be a slower build but use less memory

That did not help.


I guess there is something fundamentally wrong:
