Ps has a bug if there are more than 64 processes running and the "f"
flag is used. Krzysztof Halasa posted a fix to the source code.
Unfortunately I wasn't able to compile it because I'm missing one of
the required files.
Would some kind person please create an RPM?

Hi,
There is a bug in procps-1.01 ps.c file. ps segfaults when launched
with "-axf" ("f" is important) on system with more than 64 processes.
Hand-made fix follows (file ps.c):
void add_node(char *s, proc_t *task) {
if (maxnodes == 0) {
maxnodes = 64;
node = (struct tree_node *)
malloc(sizeof(struct tree_node) * maxnodes);
}
- if (nodes > maxnodes) {
+ if (nodes >= maxnodes) {
maxnodes *= 2;
node = (struct tree_node *)
realloc(node, sizeof(struct tree_node) * maxnodes);
}
node[nodes].proc = task;
node[nodes].pid = task->pid;
node[nodes].ppid = task->ppid;
node[nodes].line = strdup(s);
node[nodes].cmd = task->cmd;
node[nodes].cmdline = task->cmdline;
node[nodes].environ = task->environ;
node[nodes].children = 0;
node[nodes].have_parent = 0;
nodes++;
}
Please reply to <khc@hq.pm.waw.pl> if required.
