When compiling a c++ work project which uses boost-1.42.0-r2 with gcc-4.5.1-r1, I get an internal error when compiling some unit. It only happens with the -02 or -03 option, not with -O0 or -O1. I will attach the preprocessed output, in order to easily reproduce the bug with the "steps to reproduce".

Created attachment 255503 [details] preprocessed source This source file was preprocessed on an x86 arch, and will only work on an x86 arch. Uncompress the file with the "uncompress" command first (was larger than max upload size).
also fails with gcc version 4.5.2-pre9999 20101130 (prerelease) rev. 167289 (Gentoo SVN). i'll try to cut this testcase down a bit.
Created attachment 256554 [details] preprocessed source (1.6 MB) I tried to cut it down a bit as it is easier for me with the raw sources, but I only achieved 3.6M -> 1.6M. The only external headers included are now : #include "boost/numeric/ublas/vector.hpp" #include "boost/numeric/ublas/vector_proxy.hpp" Still x86, but now use gunzip to uncompress (don't know why I used compress the first time).
Created attachment 256557 [details] testcase source I managed to cut down the test case to a very simple file (the previous preprocessed source was generated with it). It only includes two files from svn+http://svn.boost.org/svn/boost/sandbox/numeric_bindings-v1/ (latest version) If I change a few details, like defining the body of the method estimateValue inside of the class declaration instead of outside, or using vector<double> instead of vector_range<vector<double> >, then it compiles fine. Hope it will help.
I managed to reduce your first example down to 10KB, it's on the upstream bug report. I'll see what i can do with this one.

Ok, I didn't notice the upstream URL, my fault. Sorry! By merging your 10KB file with my source, I could reduce it to 6KB, but I don't think it will make any difference. Tell me if you want me to post it. Just out of curiosity, you used a program to strip unused code from the preprocessed source, you didn't do it manually? Oh and sorry for the file type too :-s
I used topformflat and delta as described here: http://gcc.gnu.org/wiki/A_guide_to_testcase_reduction. They're available as app-text/delta. I think upstream has enough info now. They seem to be narrowing down the problem.
Fixed in 4.5.2.
