> There were several bugs in crash handling on Linux:
> 1) crash handler intermittently waits for "return" to continue printing (because of pipe problems);
> 2) crash handler reports file/line information for shared objects only, not for 'java' executable (because of incorrect addr2line usage);
> 3) crash handler uses incorrect width to print addresses on em64t;
> 4) there is a cause for recursive crash handling, because default signal action is set after crash handler invocation.
> Suggested patch fixes these problems.
