            Bug ID: 16244
           Summary: need a type GC
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: symtab
          Assignee: unassigned at sourceware dot org
          Reporter: tromey at redhat dot com

Right now gdb can leak "struct type" instances.
Search for FIXME-type-allocation.

There are two things to do here.
First, a "type GC" would be good, especially for types
not associated with an objfile.  The idea here is to record
all allocations done when copying a type; and then periodically
garbage collect types (using the value history, breakpoint
expressions, and Python types as roots).

Second, for types associated with an objfile, we could either use
the GC, or use "type interning" to be able to reuse range objects.
