Compilation failure with Value too large for defined data type in Gentoo

It has happened several times for the last 10 years, a program to fail during the configure stage with a strange error:

checking whether we are cross compiling...  * /var/tmp/portage/sys-apps/sandbox-2.12/work/sandbox-2.12/libsandbox/libsandbox.c:check_syscall():968: failure (Value too large for defined data type):
 * ISE: fopen_wr(conftest.out)
        abs_path: (null)
        res_path: /var/tmp/portage/sys-apps/sandbox-2.13/work/sandbox-2.13-abi_x86_32.x86/conftest.out
configure: error: in `/var/tmp/portage/sys-apps/sandbox-2.13/work/sandbox-2.13-abi_x86_32.x86':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details

It’s like the “./conftest” is made and the execution failed?

Last package it happened was when trying to build

sys-apps/sandbox-2.13

but it is not especially related to this Gentoo package or even to Gentoo!

And the debug.log is not informative neither:

After some debugging it turned out the problem was the

XFS filesystem

The root was formatted with XFS and therefore

/var/tmp/portage

where all the compilation occurred was on a xfs formatted partition!
It is easy to resolve the issue, just mount your “/var/tmp/portage” on another filesystem, if you do not have any spare devices or places with other filesystem, you could always mount it using

tmpfs

(using your memory for the directory) like this:

mount -t tmpfs -o size=4096m tmpfs /var/tmp/portage/

You can adjust the size with “size” parameter, but most of the program require a way below 4G of space. And do not forget mounting your build directory in the tmpfs speeds up the emerge process significantly!

And probably it is a good idea before mounting it to delete all old sub-directories, because they can take much space and they are left there after failed compilations of packages.

rm -R /var/tmp/portage/*

PS: It was the same with compilation of

sys-devel/gcc-7.3.0

The problem is the same, compiling on
