--- Comment #3 from Satoshi Adachi <hbjbb131 at yahoo dot co.jp> 2011-02-26 20:59:18 UTC --- (I am sorry for some delay to reply.) > There are problems with exceptions on Darwin, see PR 42159 Thank you for your information. I read PR 42159. This report mainly concerns with Darwin on Intel Macintoshes. But my report was about Darwin on PowerPC Macintoshes. There is a correction. I wrote "gcc-4.5.2 is natively built from source code on my Macintosh (PowerBook G4, MacOS X 10.5.8 (Leopard)). ". But this should be "gcc-4.5.2 is natively built from source code on my Macintosh (iBook G4, MacOS X 10.5.8 (Leopard)). ". > Please provide the information requested at http://gcc.gnu.org/bugs/ > Specifically, you didn't say what configure options you used to build gcc. * the exact version of GCC: g++ (GCC) 4.5.2 * the system type: powerpc-apple-darwin9.8.0 * the options given when GCC was configured/built: /usr/local/src/GNU/GCC/gcc-4.5.2/configure \ --enable-languages="c,c++,fortran,java,objc,obj-c++" make bootstrap sudo make install * the complete command line that triggers the bug: g++ -O2 demo.C ./a.out * the compiler output (error messages, warnings, etc.): No warning * the preprocessed file (*.i*) that triggers the bug, generated by adding -save-temps to the complete compilation command, or, in the case of a bug report for the GNAT front end, a complete set of source files (see below): I will attach the intermediate files generated by -save-temps in separate files. > You could also use a debugger to find out where it hangs. According to your suggenstion, demo.C is compiled with -g option and gdb is used to find where the program hangs.
