// fault twice with SIGSEGV (TestCrashInErrorHandler=14). The point is not only to test
|

// secondary crashes, but secondary crashes with a *different* error signal. This should
|
|
// be handled correctly and not hang/end the process (so the signal mask must be set correctly).
|
|
// See JDK-8065895.
|
|
// We do this twice, to check that secondary signal handling works repeatedly.

|
|
// the secondary error.
