amaya 3.1 dumps core, illegal instruction, on exit

I am new here, but I have had a quick look at the archives and could not
see anything like this reported.

Amaya compiled from amaya-src-3.1.tgz with gcc version egcs-2.91.66
19990314/Linux (egcs-1.1.2 release) . With -g and -O2 as default
Options.orig.
Running on pretty much a stock Redhat 6.2 installation FWIW.

I have compiled several times with a few variations, but it always dumps
core on exit. Most unlikely to be hardware problem. There are so many
warning messages during compilation that I might have missed a serious
error, but the compilation and make complete.

I attach a very short gdb transcript with a backtrace from where the
illegal instruction occured. Hope this helps.
