      Description

        Our customer reported JFR crashes on Linux ppc when filling stack trace.

        My investigation points to that Linux ppc signal handle does not install crash protection callback, as other platforms do, etc. linux_x86.

        This bug seems to be day 1 bug, probably during the porting. Thomas Stuefe refactored [1] relevant code during 16 time frame , so this bug is presented in 15 and earlier version.
