Hi.

symtab.h contains this:

struct general_symbol_info
{
 /* Name of the symbol.  This is a required field.  Storage for the
    name is allocated on the objfile_obstack for the associated
    objfile.  ...  */

 char *name;

[...]

#define DEPRECATED_SYMBOL_NAME(symbol)  (symbol)->ginfo.name

but symmisc.c does this:

static void
free_symtab_block (struct objfile *objfile, struct block *b)
{
 [...]
     xfree (DEPRECATED_SYMBOL_NAME (sym));
 [...]
}

Either the comment is incomplete (i.e. some names are not allocated
on an objfile_obstack), or the code is wrong (or in this case, outdated).

There's a FIXME that says free_symtab_block is likely never used
and that is the case.  free_contents is never used, which
is how free_symtab_block would get called.
