Hi, the attached file testcase-src-15.cxx contains a testcase which makes the compiler segfault:
amber2::wilx:~/tmp/log4cplus-svn/objdir/src/testcase> g++ -O3 -fkeep-inline-functions -c testcase-src-15.cxx testcase-src-15.cxx: In member function void PropertyConfigurator::replaceEnvironVariables(): testcase-src-15.cxx:60:30: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. Removing either -O3 or -fkeep-inline-functions removes the segfault. amber2::wilx:~/tmp/log4cplus-svn/objdir/src/testcase> g++ -v Using built-in specs.
