Hi all I obtain abort! when compiling this short program

program essai; var c:complex; begin c:=cmplx(1,5); c:=c/2.0; end.

dividing a complex by a real does not work, with * it works, even with /cmplx(2.0,0.0); What is broken ? (I work with DJGPP / gpc-19990118_i386-pc-djgppv201.zip) thanks in advance !
