Hi,
I'm attempting to track down a memory leak in my application.
I managed to run heapshot a number of times as described in the wiki
page but unfortunately, now my application fails to start every time
with the profiler enabled.
Running a debug build on ubuntu 11.04 + mono 2.10.2 produces:
[mono-2.10] ~/projects/rovisualizer-dev/rovisualizer/bin/Debug @ mono
--gc=sgen --profile=log:heapshot rovisualizer.exe

Debug info from gdb:
Could not attach to process. If your uid matches the uid of the target
process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try
again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf
ptrace: Operation not permitted.
=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
Aborted
-------------------
Any ideas?
Thanks,
Nicholas
