What version of glibc and glibc-debuginfo was this with? glibc-2.12.90-18.x86_64 glibc-debuginfo-2.12.90-18.x86_64 This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping |

Version-Release number of selected component (if applicable): firefox-3.6.12-1.fc14.x86_64 gdb-7.2-23.fc14.x86_64 gdb-heap-0.5-2.fc14.x86_64 How reproducible: Every time Steps to Reproduce: 1. Start up firefox, note the pid of the/usr/,lib64/firefox-3.6/firefox 2. Start up gdb with and attach to the appropriate process: PYTHONPATH=/usr/share/gdb-heap gdb python import heap attach 2057 # this will need to be pid for /usr/lib64/firefox-3.6/firefox 3. Attempt to print out heap info with: heap Actual results: Traceback (most recent call last): File "/usr/share/gdb-heap/heap/commands.py", line 34, in g return f(self, args, from_tty) File "/usr/share/gdb-heap/heap/commands.py", line 56, in invoke usage_list = list(iter_usage_with_progress()) File "/usr/share/gdb-heap/heap/__init__.py", line 526, in next return self.inner.next() File "/usr/share/gdb-heap/heap/__init__.py", line 550, in iter_usage for chunk in ms.iter_sbrk_chunks(): File "/usr/share/gdb-heap/heap/glibc.py", line 239, in iter_sbrk_chunks if chunk.as_address() > 0: File "/usr/share/gdb-heap/heap/__init__.py", line 125, in as_address return long(self._gdbval.cast(type_void_ptr)) RuntimeError: Invalid cast.
