# 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.
