STL mt_allocator crash in global construcutor

FC4, g++ (GCC) 4.0.2 20051125 (Red Hat 4.0.2-8) We have a no. of libraries which have worked fine up till now (even using 4.0.1 on FC3, albeit with libstdc++-3.4.4-). Now with 4.0.1 (& 4.0.2)'s libstdc, I'm getting a crash immediately at start-up in mt_allocator.h, within _M_adjust_freel

Different Object Model in g++-2.95 and g++-3.3.5?

Hi, all: I compiled the following code using g++-2.95: - #include using namespace std; class A { public: virtual void echo () {}; }; class B: public virtual A { public: int b; virtual void echo () {}; }; int main()

Re: STL mt_allocator crash in global construcutor

The correct list for this post is [EMAIL PROTECTED] I suggest that you come up with a self-contained bit of code to reproduce the problem you are having and entering it into gcc bugzilla, which can be found here: http://gcc.gnu.org/bugzilla best, benjamin

Possible size-opt patch

Bernd, I read you're interested in code-size optimizations. I'd like to point you to this patch: http://gcc.gnu.org/ml/gcc-patches/2005-05/msg00554.html which was never finished nor committed (I don't know if RTH has a newer version though). This is would be of great help for code size issues in

GCC back-ends

Hi, Does GCC front- and middle-end keep the source code line numbers all the way until the RTL is generated? I'd need that for the tool I'm developing. Also, are there any simple source code browsers / static analysis tools that use GCC as the front-/middle-end that I might check out to see ho

new gcc/g++ 4.1.0 flags?

Where exactly are the compiler flags new to gcc 4.1.0 described. I now understand that -ffriend-injection can be used with g++ to overcome the new strictness about the scope of friends. However, I am seeing another compile error in xplor-nih of the form... cdsVector.cc: In function 'CDSVector

Richard, If we have to replace the build1's with something, please let me know and I will implement it. I completely missed r107917... I will set about doing it. Paul T
