There isn't supposed to be any limitation other than your disk size - well, up to a couple of GB, anyway.

You should run 'sh -x $INFORMIXDIR/bin/esql -e -I/home/inc ownlib.ec' and check which program is core dumping. Odd are, it is $INFORMIXDIR/lib/esql/esqlc, in which case the C compiler you're using is immaterial. If the problem is in GCC (unlikely), then you need to ask elsewhere. > I Use: > IBM Informix Dynamic Server Version 9.40.UC2 On AIX 5.1 > With GCC 3.3.1 > IBM Informix CSDK Version 2.81, IBM Informix-ESQL Version 9.53.UC2 Thanks for that information! > The same code compile fine under Windows Env... with no modification at > all....

After that, you're on thin ice. We've got 1Gb Memory and 1Gb swap.... very classic for such an application And hard drive space do not seems to be a problem... (Just before having core dumped => There is a lot of disk access.... But I think that one part is Swapping, and other is writing core on disk) [....cut....] > > I can include a lot of them , but there is a limit... > > At a certain point i got : > > esql[608]: 15326 illegal instruction(coredump) > > That's not good - core dumps mean bugs.

I don't know if it would be of interest to migrate to 3.3.2 or 3.3.3.... Doesn't seems that such problem have declared on GCC list or in the change logs. sh -x.....result: ============== sh -x $INFORMIXDIR/bin/esql -e -I/home/inc ownlib.ec [cut] + [ 0 = 0 -a FALSE != TRUE ] + [ x != x ] + /home/informix/lib/esql/esqlc -I/home/inc/ -t unix ownlib.ec /home/informix/bin/esql[608]: 8612 illegal instruction(coredump) + STAT=132 + CFILE=TRUE [cut] That's it ... I'm gonna try 2 more things And then post an example code that reproduce the core. Thx !
