------- Additional Comments From wanderer at rsu dot ru 2004-12-31 17:13 ------- At this moment i can't extract simple testcase. But problem indeed in miscompiletion.
I am use modified testcase (additionl debug output line before assert (and iostream header include: std::cout << "begin==" << startpos << " end==" << endpos << "\n"; Valid output: "begin==0 end==8" Invalid output:"begin==-1 end==-1" I bootstrap GCC from current sources with additional -save-temps flag and compile and link libsupc++.a library and requred for my testcase .ii (renamed to .cc) files from libstdc++ library. Final testcase executible work without problems with valid output. But if i compile basic_file.cc (renamed .ii version) with -O2 option then testcase executible run terminated with invalid output "begin==-1 end==- 1" and assert fail. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19060
