Hi Severin,

we noticed that the Windows 32 bit build fails with the latest changes in jdk11u: cl : Command line error D8016 : '/RTC1' and '/O1' command-line options are incompatible *** [Lib-jdk.hotspot.agent.gmk:54: /output-jdk11-fastdebug/support/moduleslibs/jdk.hotspot.agent/saproc.dll] Error 1 I guess this is related to the backport of http://hg.openjdk.java.net/jdk-updates/jdk11u/rev/5dd4ef1d6ce9 Can you take a look, please?

Unfortunately I don't have a system to reproduce this on. Looking at the documentation of /RTC1[1] it's pointed out that it should only be enabled for debug builds. This suggests we need to add this flag only for slowdebug builds. It's being added here: http://hg.openjdk.java.net/jdk-updates/jdk11u/file/4675b75ee535/make/lib/Lib-jdk.hotspot.agent.gmk#l47

That is, we no longer can add that flag unconditionally. I've filed this bug: https://bugs.openjdk.java.net/browse/JDK-8212110

I'll see if I can come up with a patch which you can test.

Thanks, Severin
