Bug in execl()
---------------
Under B20.1+gcc-2.95.2 running on NT/98 under a "dos" window (not bash)
prog1.exe consists of
{signal(SIGHUP,SIG_IGN);
//some stuff
execl("prog2.exe","prog2.exe",argv[1],argv[2],argv[3],0);
return 0;}
prog2.exe consists of
{signal(SIGHUP,SIG_IGN);
// stuff
return 0;}
I pretty sure the details of the program don't matter
No problem running it , however using task manager on NT we see that
when prog2.exe is running , prog1.exe is still there when it should be
overwriten .
So a series of execl calls could easily fill up all memory , when the
only memory required is for the program currently executing
Thanks
