Subject [jira] Created: (HARMONY-1859) StackOverflowError handling leads to Segmentation fault on Linux with -Xem:opt and jet and is handled incorrectly with -Xint on both Win and Linux
Date Fri, 13 Oct 2006 09:28:35 GMT
StackOverflowError  handling leads to Segmentation fault on Linux with -Xem:opt and jet and
is handled incorrectly with -Xint on both Win and Linux 
----------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-1859
                 URL: http://issues.apache.org/jira/browse/HARMONY-1859
             Project: Harmony
          Issue Type: Bug
            Reporter: Vera Aristova
            Priority: Minor


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:
-----------------------------------------------------------------------

 export LD_LIBRARY_PATH=$HY/bin
