[mapserver-dev] getting a crash that might be 32-64 bit ro build issue related

[Stephen Woodbridge]

After spending 3 days chasing a problem that is making me nuts, I 
thought I would post this much.

It is clearly label related because if we comment out the label block it 
works fine.

I have been able to reproduce this in mapserver CGI just a short while 
ago. I will try it with 5.2 when I have a chance and let you know what 
happens.

Meanwhile, does this back trace look familiar? Thomas? Steve?

Thanks,
   -Steve
