First of all, it's nearly impossible to create a short self contained test
case, at least for me. The function get_got in bfd/elf64-ia64.c shows the
issue.
Resolving the dependencies of this function is like opening a can of worms.

What I have:
I verified that enclosing only the get_got function in 
#pragma GCC optimize ("ipa-sra", "no-inline")
.
.
#pragma GCC reset_options
yields the fault.

In contrast enclosing the get_got function in
#pragma GCC optimize ("no-ipa-sra", "no-inline")
.
.
#pragma GCC reset_options
gives a working ia64-unknown-linux-gnu-ld.

I'm attaching both versions as preprocessed source.

compiling these with gcc -g -O2 -S produces the correspondent assembler output,
also attached.
