# REQUIRES: x86
## The ELF spec says all symbols with STB_LOCAL binding precede the weak and
## global symbols. If a local symbol is found in the non-local part of the
## symbol table, make sure we have filled in all entries of InputFile::symbols.
## Otherwise a null entry can lead to a null pointer dereference when iterating
## over InputFile::symbols.
