From 4cfd3c49904429c595c893db2c733bb66fe689e5 Mon Sep 17 00:00:00 2001 From: Fred Fish Date: Fri, 22 Nov 1991 02:30:34 +0000 Subject: Initialize the c++ specific portion of the type structure for union types as well as struct types, since gdb attempts to reference that portion for both types. Was getting core dumps due to NULL pointer dereferencing. --- gdb/dwarfread.c | 32 ++++++++++++++++++-------------- 1 file changed, 18 insertions(+), 14 deletions(-) (limited to 'gdb/dwarfread.c') diff --git a/gdb/dwarfread.c b/gdb/dwarfread.c index 44e8ccf..fcc2f35 100644 --- a/gdb/dwarfread.c +++ b/gdb/dwarfread.c @@ -901,24 +901,28 @@ DEFUN(struct_type, (dip, thisdie, enddie), { type = alloc_utype (dip -> dieref, NULL); } - switch (dip -> dietag) + if (dip -> dietag == TAG_structure_type || dip -> dietag == TAG_union_type) + { + TYPE_CPLUS_SPECIFIC (type) = (struct cplus_struct_type *) + obstack_alloc (symbol_obstack, sizeof (struct cplus_struct_type)); + (void) memset (TYPE_CPLUS_SPECIFIC (type), 0, + sizeof (struct cplus_struct_type)); + if (dip -> dietag == TAG_structure_type) + { + TYPE_CODE (type) = TYPE_CODE_STRUCT; + tpart1 = "struct "; + } + else + { + TYPE_CODE (type) = TYPE_CODE_UNION; + tpart1 = "union "; + } + } + else { - case TAG_structure_type: - TYPE_CODE (type) = TYPE_CODE_STRUCT; - TYPE_CPLUS_SPECIFIC (type) - = (struct cplus_struct_type *) obstack_alloc (symbol_obstack, sizeof (struct cplus_struct_type)); - bzero (TYPE_CPLUS_SPECIFIC (type), sizeof (struct cplus_struct_type)); - tpart1 = "struct "; - break; - case TAG_union_type: - TYPE_CODE (type) = TYPE_CODE_UNION; - tpart1 = "union "; - break; - default: tpart1 = ""; SQUAWK (("missing structure or union tag")); TYPE_CODE (type) = TYPE_CODE_UNDEF; - break; } /* Some compilers try to be helpful by inventing "fake" names for anonymous enums, structures, and unions, like "~0fake".
