From: bitbug@netcom.com (James Buster) Subject: Re: gnu, malloc, and "zero'd" memory Which version of gcc are you using? I know for sure that g++ 1.42 depends upon its malloc'ed memory being zeroed. I had to modify xmalloc() to memset() the memory to zeroes before letting the compiler use it. I didn't track down exactly where such dependencies were, however. gcc 1.42 (at lease on our platform) doesn't seem to need this, but the fact that g++ needs this casts doubt upon gcc. -- James Buster bitbug@netcom.com If you found that changing xmalloc in the way you described changed the behavior of the compiler, then you have found a bug. By not reporting the bug in the proper fashion, you leave yourself and others open to potential problems in the future. This is irresponsible. Without knowledge of what is the exact bug in G++ 1.42, I don't see why you choose to cast doubt on GCC 1.42. That does nothing but cast doubt onto all GNU software--doubt which stems from ignorance, not inference nor intelligence. Michael
