I am taking back my previous statement, I forgot to compile with
--enable-assert in the 4.5 branch.

Testcase asserts in all:
trunk r158095 (ipa-reference.c:731)
4.5 r158131 (ipa-reference.c:731)
4.4 r158133 (ipa-reference.c:697)

This stopped crashing sometimes between r158969 and r159387 (at x86_64-linux)
