[Mono-list] My program randomly doesn't work with Mono

[Jonathan Gagnon]

I use Fedora Core 3 and mono 1.2.3.1.  I get the same problem when using
mono 1.2.4.  I  wanted to attach the outfile generated by heap-buddy but it
is too large for the mono-list.  I attached the "backtraces" and the "types"
outputs instead.  Here's the summary :
 
           SUMMARY
 
         Filename: outfile
  Allocated Bytes: 228.3M
Allocated Objects: 5000070
              GCs: 12
          Resizes: 328
  Final heap size: 2725.3M
 
   Distinct Types: 8
       Backtraces: 14

Can i get both of you experiencing problems to either run your applications
with heap-prof or heap-buddy to generate some profiling statistics to help
figure out whats going wrong on your particular setup?

Also, what OS's and mono versions are you on that are causing these
problems? Is the behaviour the same with mono 1.2.4? Please test that before
filing any bug reports.

Alan.

The problem is intermittent. I can work on my program all day and
then suddenly it just starts failing. Stick a Console.WriteLine in
and it works again. Then it stops again and I take it out and it
works again!
