4GL app segmentation fault on Solaris (Sparc) w/gcc

I've got a bizzare problem that's killing me. Here's the scoop: Sparcstation 5 clone (Integrix) running Solaris 2.4 Informix SE ver 7.11.UC1 Informix 4GL ver 6.02.UC1 Gnu C compiler verison 2.5.6 or 2.7.0 (tried them both) Some of my programs compile and run just fine, others coredump with a segmentation fault immediately upon entering the statement "INPUT BY NAME <my list of fields go here>". I've checked all the usual stuff like making sure the screen fits inside the window, the termcap entry looks good (the stock "sun" console entry and a vt100 entry for a pc termulator telnetted into the workstation). These exact same programs compile and run perfectly on either an HP9000 system or a SCO system which I've compiled them upon. Is gcc just not very stable with i4GL? Some of my apps run perfectly on this little sparc box. The only other difference between the unix boxes upon which I've been troubleshooting this problem is that the HP9000 is running Online DSA 7.10 and the SCO box is running Online 5. Has anyone else ran into similar problems and know a workaround? I really can't afford to buy Sun's C compiler right now so if anyone can help me out here, I'd really appreciate it.
