           Summary: 3.3: ICE with -gstabs when including STL headers
           Product: gcc
           Version: 3.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: lloyd at randombit dot net
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: i686-linux
  GCC host triplet: i686-linux
GCC target triplet: i686-linux

Including virtually any STL header and attempting to compile with -gstabs with
GCC 3.3 causes an ICE on x86/Linux. I'm using glibc 2.2.5 and binutils
2.11.93.0.2, though I doubt either is relevant here. Using other debug flags,
like -gstabs+, -gdwarf, -gdwarf-2, etc, seems to work fine.

$ cat stabsbug.cpp 
#include <vector>

int main() { return 0; }

$ g++-3.3 -gstabs stabsbug.cpp -c -o /dev/null

Confirmed on 3.3.1 (20030707) and the mainline (20030708),
Simplified example:
struct t{};
struct g : public t{};

Indeed confirmed with Andrew's small testcase. This is a regression w.r.t.
3.2, where it worked.

A backtrace on mainline looks like this:
#0  host_integerp (t=0x0, pos=0) at ../../gcc/gcc/tree.c:3251
#1  0x08600ca0 in ?? ()
#2  0x083b7cb9 in tree_low_cst (t=0x0, pos=0) at ../../gcc/gcc/tree.c:3270
#3  0x081b7750 in dbxout_type (type=0x403d98dc, full=1)
    at ../../gcc/gcc/dbxout.c:1659
#4  0x081b8ef5 in dbxout_symbol (decl=0x403d9a20, local=0)
    at ../../gcc/gcc/dbxout.c:2124
#5  0x083a8635 in rest_of_type_compilation (type=0x403d98dc, toplev=1077778976)
    at ../../gcc/gcc/toplev.c:2406
#6  0x080cf588 in finish_struct_1 (t=0x1) at ../../gcc/gcc/cp/class.c:5213
#7  0x080d0296 in finish_struct (t=0x403d98dc, attributes=0x0)
    at ../../gcc/gcc/cp/class.c:5271
#8  0x0813dd8a in finish_class_definition (t=0x403d98dc, attributes=0x0, 
    semi=1, pop_scope_p=0) at ../../gcc/gcc/cp/semantics.c:2033

So it's really a problem in the debug backends, rather than the C++ front
end (of course).

W.

In that case this is probably a dupe of bug 7083, though it's odd, because that
bug was for GCC 3.1, and I didn't run into this with 3.1 or 3.2. Hrm.

------- Additional Comments From steven at gcc dot gnu dot org  2003-07-12 12:20 -------
The problem is apparently in dbxout.c:dbxout_type:

		print_wide_int (tree_low_cst (DECL_SIZE
					      (TYPE_NAME
					       (BINFO_TYPE (child))),
					      0)
				* BITS_PER_UNIT);

But the tree for DECL_SIZE that is passed is NULL.

Is this really target specific?
