Due to a suspected problem in the way systemtap/elfutils compute PC addresses to place int3 probe breakpoints into prelinked shared libraries, sometimes the wrong instruction is modified. This can lead to lost probes, or segmentation violations, or more subtle errors. This problem appears to exist in all versions of systemtap. "prelink -u /usr/lib/libFOO.so" corrects the miscalculations, as a temporary workaround. This issue is being tracked upstream at http://sourceware.org/bugzilla/show_bug.cgi?id=12141
Bug is in libdwfl handling of prelink REL->RELA changes vs separate debug file.
commit 1743d7f should fix this, needs more thorough/regression testing still.
