Re: [PATCH] gdb script performance

When the user changes the symbol file (or when GDB notices it has changed and automatically re-reads it), the section and symtab objects your static variables are pointing to will be freed. If you then get a spurious cache hit, you'll hand out a pointer to garbage. So you'll need to invalidate the cache whenever the section or symtab get freed.

Yes, that's what I meant when I said that hooks for invalidating the caches are missing, but I haven't looked yet where they should be added.


BTW I don't know if the test suite would catch this; if not, a test should probably be added.
