Hi - I'm running on a fairly stock RedHat 6.1 box. The program I'm writing makes extensive use of "complex<double>". I'm using egcs-1.1.2 and was originally using gdb-4.18. gdb-4.18 seemed to be completely incapable of displaying complex<double>: (gdb) print sample[0] $1 = <incomplete type> I then upgraded my gdb to the latest release from RedHat rawhide stuff: gdb 19991004. This new release worked better, initially it tends to display the complex<double> properly, but if I recompile and reload the debugging symbols it reverts back to the <incomplete type> behavior. regards - Jon
