585925 - testIsAboutToBeFinalized_bug528645 | CHECK failed: JSString::isStatic(p)

Status: RESOLVED INCOMPLETE

(Core :: JavaScript Engine, defect)

Description

[Ginn Chen]

It happens on latest m-c and t-m.
Compiler is Sun Studio 12.1
If I compile js with -xO2, the test passes.
If I compile both jsapi.o and jscntxt.o with -xO3, the test fails.
If I comment out CHECK(JSString::isStatic(p)); in the test cpp file,
CHECK(checkPointersStaticStrings == 0); would pass.

So it is fragile.

I guess the problem is the test case itself,
NativeFrameCleaner() probably does not always work as expected on SPARC.
(because of register windows?)

Any suggestions how to reset the regs?
