That used to work in previous versions of the glibc such as the one we shipped in RHEL4 Version-Release number of selected component (if applicable): glibc-2.5-24 How reproducible: 100% reproducible Steps to Reproduce: 1. LD_PROFILE_OUTPUT=${PWD} LD_PROFILE=libgtk-x11-2.0.so.0 gnome-calculator 2. sprof libgtk-x11-2.0.so.0 3. Actual results: sprof: failed to load shared object `libgtk-x11-2.0.so.0' Expected results: Flat profile: Each sample counts as 0.01 seconds. % cumulative self self total time seconds seconds calls us/call us/call name index % time self children called name [0] 0.0 0.00 0.00 0 g_param_spec_object [0] ... Additional info: The bug was introduced in dlfcn/dlopen.c in dlopen_doit() by adding a mask for the mode and that mode is missing __RTLD_SPROF so that sprof cannot open the shared lib. The patch attached adds __RTLD_SPROF to the mode mode so that sprof works.

It might be that we can use some of the userspace stap stuff. Evidently it is beginning to show up in 5.3.

Hi Ajax, You might use "man stapprobes" on with the systemtap-0.7.2-1.el5 in RHELU3 beta for more information on user-space probes. -Will This event sent from IssueTracker by woodard issue 197199 it_file 169209 Reply at: https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/462760/comments/3 ------------------------------------------------------------------------ On 2009-01-20T20:50:40+00:00 errata-xmlrpc wrote: An advisory has been issued which should help the problem described in this bug report.
