--- Comment #7 from Yuri <yuri at tsoft dot com> 2011-01-30 22:03:50 UTC --- Actually g++ produces the correct assembler file, but still calls original Sun assembler /usr/ccs/bin/as instead of the GNU one from the path, regardless of the option --with-gnu-as passed to gcc configure. Removing /usr/ccs/bin/as fixes the problem. So there are two issues with gcc-4.5.2 on Solaris: 1. Inability to detect GNU assembler in path (unwarranted requirement to pass --with-gnu-as). Broken build when either no GNU assembler in path or no option --with-gnu-as passed. 2. GNU assembler from path isn't used by g++, causing Sun assembler to fail on GNU-formatted assembler file.
