[Bug 1142654] New: libstdc++.so misses SDT probes
http://bugzilla.suse.com/show_bug.cgi?id=1142654 Bug ID: 1142654 Summary: libstdc++.so misses SDT probes Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Development Assignee: bnc-team-screening@forge.provo.novell.com Reporter: tdevries@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- There's a gdb feature (since v7.10, 2015) that allows to set a catchpoint using a regexp. There's a limitation mentioned in the docs ( https://sourceware.org/gdb/current/onlinedocs/gdb/Set-Catchpoints.html#Set-C... ): ... The regular expression feature and the $_exception convenience variable rely on the presence of some SDT probes in libstdc++. If these probes are not present, then these features cannot be used. These probes were first available in the GCC 4.8 release, but whether or not they are available in your GCC also depends on how it was built. ... AFAICT, on my Leap 15.0 system, libstdc++.so does not have these SDT probes, which is why I ran into this ( https://sourceware.org/bugzilla/show_bug.cgi?id=24830 ) gdb testsuite failure. -- You are receiving this mail because: You are on the CC list for the bug.

From what I see the libstdc++ configury detects the presence of
and then libsupc++/unwind-cxx.h enables the probes unconditionally (for catch,
