      Description

        A fastdebug JVM build with GCC version 5 asserts in phaseX.cpp:1538 with:
        assert(t0->isa_int()->_widen <= t->isa_int()->_widen) failed: widen increases

        Note that a current fastdebug build of the hs-rt forest compiles hotspot with "-O3 -O0". Not sure why. In order to reproduce the issue, one needs to build hotspot with -DASSERT and -O3 (no -O0).

        Then the reproducer in order to trigger the assertion is compiling "HelloWorld.java":
        ./build/linux-x86_64-normal-server-fastdebug/images/jdk/bin/javac -d . HelloWorld.java
