I dunno. If you can't track down exactly where the crash is happening, it'll be very hard to tell anything... can you compile it with the '-ggdb' flag, then run it like this:
I also notice that, since you're using cout, your messages aren't necessarily getting printed when you think they are -- it buffers. If it crashes before the buffer is flushed, it won't get printed, even if the cout call happened first. Even explicit flushing doesn't seem to help that on some systems. Try fprintf instead:
stderr never buffers.
It also helps in debugging that fprintf is one single function call, while cout is as many function calls as there are << paramaters...

hi,
I have made a small C program that make use of malloc and free for processing bitmap images. when i try to run the program, I am getting a error something like

I am not sure of which free() is causing this... (1 Reply)

there seems not to be error in this segment. In some computers, it can work well. But in others, it will give a failure.
why it ocurrs and how to deal with it?

if( *ver == NULL ) {
*ver = (vertex *) malloc(sizeof(vertex)); //this line

Hi,
I am having a hell of a time getting this to work. So basically, I have opened a popen to run a program that is going to prompt an action to occur half way through, when it gets to this I need to create a separate process and do some stuff, then return to the original process. This works... (0 Replies)

I am facing a problem of memory corruption. The loop runs for the first time but does not go through the second time. What could be the problem?

gzexe
GZEXE(1) General Commands Manual GZEXE(1)NAME
gzexe - compress executable files in place
SYNOPSIS
gzexe name ...
DESCRIPTION
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a
penalty in performance). For example if you execute ``gzexe /usr/bin/gdb'' it will create the following two files:
-rwxr-xr-x 1 root root 1026675 Jun 7 13:53 /usr/bin/gdb
-rwxr-xr-x 1 root root 2304524 May 30 13:02 /usr/bin/gdb~
/usr/bin/gdb~ is the original file and /usr/bin/gdb is the self-uncompressing executable file. You can remove /usr/bin/gdb~ once you are
sure that /usr/bin/gdb works properly.
This utility is most useful on systems with very small disks.
OPTIONS -d Decompress the given executables instead of compressing them.
SEE ALSO gzip(1), znew(1), zmore(1), zcmp(1), zforce(1)CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the
PATH environment variable to find gzip and some standard utilities (basename, chmod, ln, mkdir, mktemp, rm, sleep, and tail).
BUGS
gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases,
using chmod or chown.
