Version: 3.2.2 (using KDE 3.4.2, Kubuntu Package 4:3.4.2-0ubuntu0hoary1 ) Compiler: gcc version 3.3.5 (Debian 1:3.3.5-8ubuntu2) OS: Linux (i686) release 2.6.10-5-386 Kdevelop consumes too much RAM when importing the C++ header file ~/libxorp/callback_debug.hh from the XORP 1.1 release (http://xorp.org/downloads.html) into a project (Menu Project->Import). It seems that kdevelop does not crash, but it consumes so much RAM when importing header files with many template parameters, that it eats up all RAM of a "normal PC", which "only" have a few GiB of RAM. This header file is generated with the pyhton script ~/libxorp/callback-gen.py (see comment at the top of the file): python callback-gen-py -d -b 6 -l 15 > callback_debug.hh kdevelop has no problems opening/highlighting the file without import into a project, nor has it problems with the non-debug version ~/libxorp/callback_nodebug.hh, (generated as above, but without option -d). I've played a bit with the generator script. On my notebook (Pentium M 2 GHz, 1 GiB RAM, 2 GiB swap) I was able to import a header file generated with parameters up to b=l=6, or up to b=2 and l=16, which both consume about 2 GiB of virtual RAM during parsing. It took e few minutes to parse the file. After parsing, the memory consuption falls back to normal levels (about 150 MiB).

Comment on attachment 11983 [details] pyhton generator script use python callback-gen.py -d -b 6 -l 15 > callback_debug.hh python callback-gen.py -b 6 -l 15 > callback_nodebug.hh
callback_debug.hh is too big (1,8 MiB) to be attached, but to give an impression of the generated classes, here are the last few lines of callback_debug.hh: /** * Factory function that creates a callback object targetted at a * const member function with 15 dispatch time arguments and 6 bound arguments. */ template <class R, class O, class A1, class A2, class A3, class A4, class A5, class A6, class A7, class A8, class A9, class A10, class A11, class A12, class A13, class A14, class A15, class BA1, class BA2, class BA3, class BA4, class BA5, class BA6> typename XorpCallback15<R, A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A11, A12, A13, A14, A15>::RefPtr dbg_callback(const char* file, int line, O& o, R (O::*p)(A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A11, A12, A13, A14, A15, BA1, BA2, BA3, BA4, BA5, BA6) const, BA1 ba1, BA2 ba2, BA3 ba3, BA4 ba4, BA5 ba5, BA6 ba6) { return XorpConstMemberCallbackFactory15B6<R, O, A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A11, A12, A13, A14, A15, BA1, BA2, BA3, BA4, BA5, BA6, BaseAndDerived<CallbackSafeObject, O>::True>::make(file, line, &o, p, ba1, ba2, ba3, ba4, ba5, ba6); }

Moving all the bugs from the CPP Parser. It was not well defined the difference between it and C++ Language Support and people kept reporting in both places indistinctively
