>Organization:
>Environment:
Cross compiling from linux to mingw, resultant code was run in win98.
>Description:
When throwing a java exception, sometimes the EH code will segfault in _Unwind_SjLj_RaiseException when attempting to invoke the personality function. Although the bug only happens sometimes, it *always* happens for the program included in the "how-to-repeat" section.

This is a regression; trunk as of 12-Dec-2001 did not have this problem; 13-Dec-2001 does. See email referenced in 'fix' section for further analysis of the ChangeLog entry which caused the bug.
>How-To-Repeat:
public class foo {
public void main(String[] s) {
try{
throw new Exception();
} catch (Exception e) {
}
}
}
