Package: linux-tools-3.0.0 Version: 3.0.0-1 Severity: normal
I captured a few perf traces on a live system (using "perf record --event cpu-clock --freq 1000 -a --output=mylog.perf"). When I try to run a report on those perf logs, it segfaults. I can run it under gdb and get a stacktrace (below). If I install the linux-source package, expand it, and do a "make" in tools/perf, then that version of perf works (no segfault). The version I built does reference different shared libraries (according to ldd). Most notably, it include libbfd-2.21.52-system.20110606.so. I believe that cplus_demangle is only called if bfd is not present(?) Stacktrace from gdb: Program received signal SIGSEGV, Segmentation fault. 0x000000000047630f in ??
