Still crashes for me.

You need to pass --build=sparc64-sun-solaris2.11 and start with a 64-bit compiler.

You need to pass > --build=sparc64-sun-solaris2.11 and start with a 64-bit compiler. I fear you're right: it occured to me that the GCC 3.4.3 I started with didn't have proper multilib support. I had started with gcc3.4.3 -m64 (which would have been a 64-bit compiler), but forgot to specify the correct target triplet, though I'm pretty sure I did so when I first reported the bug. I've now used a 32-bit gcc 4.4.0 with -m64 as bootstrap compiler and specified --build=sparcv9-sun-solaris2.10. This time, the bootstrap finished, so this has been pilot error ;-( Rainer
