* More Information

Tested the gcc that build with following commands can reproduce this problem.

wget https://ftp.gnu.org/gnu/gcc/gcc-8.1.0/gcc-8.1.0.tar.xz
tar -Jxf gcc-8.1.0.tar.xz
./configure --enable-languages=c --disable-multilib
make
make install


Then test it with

ulimit -m 1500000 -v 1500000
/usr/local/bin/gcc ubd_kern.i
