Bug ID: 87289
Summary: jdk11 plinux compiled with gcc 7.3 doesn't work with
NativeImageBuffer
Product: gcc
Version: 7.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: pdbain at ca dot ibm.com
Target Milestone: ---

Test code and sample source code
Further to https://github.com/eclipse/openj9/issues/2788
GCC does not compile "jnicsup.cpp" correctly when optimization is enabled.
It appears that "pushArguments()" is not placing the correct data on the Java
stack.
Inserting a printf makes the test pass.
To reproduce:
download and build OpenJ9 per instructions in
https://www.eclipse.org/openj9/oj9_build.html (use "git clone
https://github.com/ibmruntimes/openj9-openjdk-jdk11";). Replace
"openj9/runtime/vm/jnicsup.cpp" with the copy from the attached archive. Enable
or disable the printf on line 522.
To test, put "testgras.class" in the current directory and run
"java testgras"
(the "java" command will be in a directory called
"build/linux-ppc64le-normal-server-release/images/jdk/bin")
If the test is successful, no exception is thrown.
This bug may date back to version 5.
