It seems the location info is simply broken: (gdb) bt #0 0xb7e4e068 in strcmp () from /lib/libc.so.6 #1 0x08621600 in splay_tree_splay (sp=0x880d3e0, key=0) at ../../gcc/libiberty/splay-tree.c:148 #2 0x08621be9 in splay_tree_lookup (sp=0x880d3e0, key=0) at ../../gcc/libiberty/splay-tree.c:389 #3 0x08144c79 in get_fileinfo (name=0x0) at ../../gcc/gcc/c-lex.c:114 #4 0x080b14cc in cxx_make_type (code=RECORD_TYPE) at ../../gcc/gcc/cp/lex.c:834 (gdb) l 829 } 830 831 /* Set up some flags that give proper default behavior. */ 832 if (IS_AGGR_TYPE_CODE (code)) 833 { 834 struct c_fileinfo *finfo = get_fileinfo (input_filename); 835 SET_CLASSTYPE_INTERFACE_UNKNOWN_X (t, finfo->interface_unknown); 836 CLASSTYPE_INTERFACE_ONLY (t) = finfo->interface_only; 837 } 838 input_filename (== LOCATION_FILE(input_location) is zero. (gdb) p input_location $6 = 122 (gdb) p expand_location(input_location) $5 = {file = 0x0, line = 0, column = 0} Sigh. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

https://bugzilla.novell.com/show_bug.cgi?id=444153 User matz@novell.com added comment https://bugzilla.novell.com/show_bug.cgi?id=444153#c7 --- Comment #7 from Michael Matz 2008-11-19 07:11:06 MST --- Actually, I don't see how the current implementation could ever work in this scheme (indirectly including the pch). Basically reading in the pch file completely overwrites the line_table, i.e. all location cookies become invalid. That's normally no problem, because also those are read back in (e.g. the builtins have such cookie, but they too live in GC memory, hence are also overwritten). But the location cookies for the in-between #include directive of course isn't in the pch file, only in memory. And that one becomes invalid definitely. Reading http://gcc.gnu.org/ml/gcc/2005-03/msg01318.html (about interaction of PCH and mapped-locations) it seems as if their mental model was that indeed the precompiled header must be included from the top-level, i.e. the main file. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
