SEGV with IRRToolSet 4.8.5 on Solaris

[MMC]

Hi,
I'm having a bit of problem with IRRToolSet 4.8.5 on Solaris 10 (32bit 
on i386 FWIW).

I'm seeking help because this is stopping me having a version that will 
enable me to get on enabling EBGP peers and transit on IPv6!

I can build it just fine, and it works with import statements, but 
generating some export statements for Cisco routers causes it to SEGV.   
They worked fine on 4.7.1 and the contents of our database pass 
rpslcheck on 4.8.5 just fine. 

I've changed some IPs and ASes to protect the less innocent - I'm happy 
to supply more details off list if someone is able to help me out (I'm 
just not a C++ expert).

(gdb) set args -h myrawhoserver -p 43 -protocol rawhoisd -config cisco 
-cisco_use_prefix_lists -supress_martian
