• Type: Bug

Description

Simple recursive method calling leads to Segmentation fault instead of StackOverflowError throwing on Linux with -Xem:opt and jet.
It is handled incorrectly with -Xint on both Win and Linux .
On Windows with -Xem:opt and jet StackOverflowError is thrown correctly.

test for reproducing:

public class test {
public static void main(String [] args) {
try

{ main(args); }

catch (Throwable e)

{ System.out.println("was caught " + e); }

}
}
to reproduce run script: bash run_lnx.sh
To reproduce bash run.sh:
