It's for an internal assertion failure during static process startup.

The dynamic linker currently redefines __assert_fail to something that
does not use signals (see elf/dl-minimal.c).  However, we should
probably generate coredumps for ld.so assertion failures, too, so I
would like to change that eventually.
