This affects me too with binutils 2.25.0 on Arch Linux.
Added a two tests that also fail @ https://gist.github.com/9b701e4194c6c4e6cfb1

I bisected this using the script @ https://gist.github.com/7d4007a2c18c62a1d84d
It discovers the bad commit to be 492e19d098f4bf4f22bac22815e9cb117be55b33

There is a patch proposed by Pedro Alves for PR61321, and it fixes all
testcases mentioned here, but the patch did not get into mainline
unfortunately.
Updated testcases (valid with applied patch, cause segfault wihout patch):
_ZNmlIvEES_IDTcvT__EEES_ -> operator*<decltype ((void)())>
operator*<void>(operator*)
_ZNpLImEEN9Enable_IfIXgtcvT_1ELi0EEEES_ -> Enable_If<(((unsigned long)E)>(0))>
operator+=<unsigned long>(operator+=)
_ZNmlILelEEEN8QuantityIDTmlcvT_T_1EEEES_ -> Quantity<decltype ((((long
double)[l])((long double)[l]))*E)> operator*<(long double)[l]>(operator*)
_ZN1eIhEEN8EnableIfIXgecvT_Li0EcvS__EEEEi -> EnableIf<((unsigned
char)(0))>=((e)())> e<unsigned char>(int)
