[Mono-list] Profiling is not working?

[fsmac]

Thanks Rodrigo.

On Linux (CentOS 5.3, with mono-2.4.2.3 and mono-tools 2.4.2 compiled from
sources), statistical profiling still does not seem to work. If I run

    % mono --profile=logging:s MyApp.exe ....

I get totally random errors in MyApp.exe, from Directory.FileExists() saying
files that are there do not exist, to crashing in FSharp type initialization
code, to just SIGABRT. Is that a known issue?

It seems like logging:c allows my app to run as intended and I am trying
this right now, though this is much much slower.

YA

PS: mono-tools didn't compile fully, with GDI errors compiling gendarme
(adding a .png into a res file) and some other GLib exception (missing an
exception type), but mprof-decoder did compile properly, and the profiler
itself is in the main mono source tree, right?
