Bug ID: 16426
Summary: memory corruption (use after free) with fission
Product: gdb
Version: HEAD
Status: NEW
Severity: normal
Priority: P2
Component: symtab
Assignee: unassigned at sourceware dot org
Reporter: dje at google dot com
I'm seeing several failures in mi-var-cmd.exp when using Fission.
I've traced the problem to demangled_names_hash.
The hash table lives in per_bfd space and while the symbol name is also
supposed to live in per_bfd space, when using dwo files it lives in the per_bfd
space of the dwo which is freed when the objfile is freed.
