You don't need to do this, of course, but it shouldn't harm.

This is almost certainly a compiler bug.  The compiler addressed
non-existent memory, and the system killed it.

It's just barely possible that there are other reasons, for example,
memory errors or such, but most likely it didn't like the source,
which would suggest that the source is corrupt.  Typically, when
building the kernel, you'll see things like

gcc -c -O -W -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit  -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes  -Winline -Wunused -g -nostdinc -I. -I../.. -I../../sys -I../../../include -DI486_CPU -DIPI_VJ -DHARDFONTS -DSCSIDEBUG -DIPACCT -DCOMPAT_43 -DCD9660 -DMSDOSFS -DNFS -DFFS -DINET -DKERNEL  ../../libkern/strlen.c
gcc -c -O -W -Wreturn-type -Wcomment -Wredundant-decls -Wimplicit  -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes  -Winline -Wunused -g -nostdinc -I. -I../.. -I../../sys -I../../../include -DI486_CPU -DIPI_VJ -DHARDFONTS -DSCSIDEBUG -DIPACCT -DCOMPAT_43 -DCD9660 -DMSDOSFS -DNFS -DFFS -DINET -DKERNEL  ../../libkern/strncmp.c

These are the compiler invocations for the files strlen.c and
strncmp.c.  Check which file causes the compiler to fail, then try
again.  If it fails in the same place, there's probably something
wrong with the source (so check it).  If it fails at random places,
there's probably something wrong with your hardware.
