I want to add that segfault goes away if testcase is compiled with -fno-ipa-sra
option.

Also, the crash itself is a stack overflow because of infinite recursion in 
config/mips/mips.c:

mips_find_pic_call_symbol -> mips_pic_call_symbol_from_set ->
mips_find_pic_call_symbol -> ...

I am not sure I understand what condition does not allow the recursion to
break.
