Um, sorry. That obviously looks wrong because of optimization. Here is
what it says without -O2:
(gdb) p *pst
$1 = {next = 0x1052a018, filename = 0x1052a0e8 "../../gcc/gcc/libgcc2.c",
fullname = 0x0, objfile = 0x10148238, section_offsets = 0x1014e440,
textlow = 4922848, texthigh = 4922848, dependencies = 0x1052a118,
number_of_dependencies = 4, globals_offset = 1151, n_global_syms = 2,
statics_offset = 24280, n_static_syms = 21, symtab = 0x0,
read_symtab = 0x4f1170 <dbx_psymtab_to_symtab>,
read_symtab_private = 0x1052a100 "D\030\031", readin = 0 '\0'}
