Re: GNU ld 2.11 bug on Solaris 2.8?

[Brian Shaft]

I have seen the same thing for C compiles on gcc 2.95.3 with ld 2.10.1. It seems
to be caused by the pointer to _DTOR_LIST being zero. I avoided it by removing
-with-gnu-ld in the configure parameters. It is on my list to characterise the
problem further, but a simple check in __do__global__dtors__aux should detour
the problem if the dig into bfd does not come up with the answer.

Beware, gcc uses the presence of ld in its install directory to decide which ld
to run - so if you build binutils after you build gcc it will pick it up for
subsequent use. I ended up just removing the relevant copy after the make.
