Hi,
Could you test this patch?
http://cr.openjdk.java.net/~zgu/JDK-8234270/webrev.00/index.html
I was able to reproduce original bug with
compiler/codecache/stress/UnexpectedDeoptimizationTest.java + NMT, newly
added assertion caught the problem.
I also fixed the new test failure on Windows. JDK-8204128 patch missed
one long -> ssize_t change. long on Windows is 4-bytes vs 8-bytes on
other 64-bits platforms, that explains why it only fails on Windows.
This patch passed submit test.
[Mach5] mach5-one-zgu-JDK-8234270-1-20191117-1425-6784823: PASSED
Thanks,
-Zhengyu
