Expected Results: It should have compiled ;) Additional info: I can't send you complete source, but if you need more information, I can send you portions of it. Let me know.
Best would be preprocessed source for this file (ie. what gcc -save-temps creates). If that is impossible to send, please try more recent gcc first (e.g. from ftp://ftp.redhat.com/pub/redhat/linux/beta/taroon/en/as/i386/RedHat/RPMS ) and if the problem persists, try to distill from SERP_FISH.ii minimal part which still reproduces the problem and you can send to us). You can mail it to me privately if you don't want anybody else to see the testcase.
I have isolated the problem. The line the error refers to in my source is calling the constructor for SERP_Filter. SERP_Filter is templated on Signal. The class used as Signal has an integer member called "D". The SERP_Filter class has an member "double estimate[Signal::D]" which is what is causing the problem. Hardcoding the array size worked around the problem. Note: I have reproduced the problem using both the taroon and cvs versions of gcc. I have e-mailed the .ii file to Jakub. If anyone else would like to work on this bug, please contact me and I will send you the code. I prefer not to publicly post it.
Just hit this bug, googled and came across this bug report. I`ve reduced my code to the smallest possible size, maybe this will help someone. $ cat test.cpp class Base { public: virtual void member(); }; template<class F> void function(F func) { class Derived: public Base { void member() { new Derived(*this); } }; new Derived; } void instantiate(){ function(0); } $ g++ -c test.cpp test.cpp: In member function `void function(F)::Derived::member() [with F = int]': test.cpp:10: instantiated from here test.cpp:7: Internal compiler error in find_function_data, at function.c:330 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
Jakub didn't save the .ii file from the original problem into the PR as he ought to have done, but I can confirm that the second problem persists through to gcc 4.0. Pushed upstream to http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17823
