--- Comment #2 from christophe.lyon at st dot com 2012-01-30 09:23:27 UTC --- I noticed this about an official release; I am not sure which one it was when I entered this report, but it is at least true for GCC-4.6.2. I have just checked http://gcc.gnu.org/viewcvs/trunk/gcc/configure?revision=183406&view=markup which seems to be the current trunk version of GCC's configure and can still see: lt_simple_compile_test_code="int some_variable = 0;" at line 14904 So, when this is used when testing for -fno-rtti -fno-exceptions, it makes the test fail. I am not regenerating configure.
