I am having a really strange problem using DJGPP's gnu++ compiler and DV/X.
I am porting a program from an SGI x-window program that I wrote from
scratch.  When I try to compile the *exact* same code multiple times, it 
will compile and link but will run to completion only itermittantly.  Attached
is a .log file of ten make sessions (using qmake).  The file was made 
successfully every time, but died at different locations on each run.  The 
makes were done one after the next without any intervening calls.  The 
.log file was edited for space.
	Any suggestions on why this could be happening?

thanks in advance,


mike
