Bug #: 51032
Summary: ICE in dbxout_type, at dbxout.c:2372
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: r...@gcc.gnu.org
CC: ja...@gcc.gnu.org
Host: alpha-dec-osf5.1b, i386-pc-solaris2.11
Target: alpha-dec-osf5.1b, i386-pc-solaris2.11
Build: alpha-dec-osf5.1b, i386-pc-solaris2.11
Between r180960 and r181158 Tru64 UNIX bootstrap got broken compiling the
stage1
libstdc++. The bug can be broken down to
$ ./cc1plus -fpreprocessed stdc++.ii -quiet -mieee -g -O2 -std=gnu++11 -o
stdc++.s

internal compiler error: in dbxout_type, at dbxout.c:2372
Since gdb chokes on cc1plus on osf and this seemed to be a stabs issue, I tried
a corresponding invocation (from the -save-temps output of generating
i386-pc-solaris2.11/bits/stdc++.h.gch/O2ggnu++0x.gch) on Solaris 11/x86, but
with -gstabs instead of the default, DWARF-2. I get the same error:
$ ./cc1plus -fpreprocessed stdc++.ii -quiet -gstabs+ -std=gnu++11 -o stdc++.s
[...].

In gdb, I find that dbxout_type cannot deal with
<template_type_parm fb9fb120 _Up type_0 type_6 VOID
