Status: RESOLVED FIXED

(Developer Infrastructure :: Source Code Analysis, defect)

Description

[Pedro Lamarão]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; pt-BR; rv:1.9.1b4) Gecko/20090427 Fedora/3.5-0.20.beta4.fc11 Firefox/3.5b4
Build Identifier: 

GCC 4.5 with Dehydra triggers an ICE compiling <iostream> and <iterator>; the error message suggests both files trigger the same ICE.

Reproducible: Always

Steps to Reproduce:
1. Compile one of the pre-processed source files.

Actual Results:  
Internal compiler error.

Expected Results:  
Successful compilation.

Using an empty script for smoke testing.

Attachment: workaround

I *think* this is a case of dehydra needlessly triggering a gcc bug. This is a workaround. Let me know how it works out for you

Also for simple testcases like this it's sufficient to say that "including <iterator> causes ICE" don't need the .ii files in that case.

Comment 4

[Pedro Lamarão]

Confirmed.
With this patch, I can compile and run the dumptypes.js script, from the "Using Dehydra" page, the following standard headers:

#include <algorithm>
#include <deque>
#include <exception>
#include <functional>
#include <iostream>
#include <iterator>
#include <list>
#include <map>
#include <memory>
#include <stdexcept>
#include <string>
#include <utility>
#include <vector>

either stand alone or all together in a translation unit.

I'll try to add these tests to the test suite.
