(I.e. setting the PATH and LD_LIBRARY_PATH such that 4.6.0 is used.) For curiosity, I will try to compile without bootstrapping with 4.5.1 20101208 [gcc-4_5-branch revision 167585] However, it looks as if GCC 4.5.0 miscompiles f951; except for not bootstrapping, there should be no difference between --disable-bootstrap and not. (Contrary to --enable-checking=release.)
