Description christor 2000-04-05 15:50:01 UTC 
The gprof program seems to want to use an enormous amount of memory, even for very simple programs.

On my system at home (uname -a output: FreeBSD laptop.smurfy.net 3.3-RELEASE FreeBSD 3.3-RELEASE #5: Tue Mar 28 17:06:51 EST 2000     chris@laptop.smurfy.net:/usr/src/sys/compile/LAPTOP  i386) I get the output:

Killed

In addition, the output "swap_pager: out of swap space" is sent to the console.

On a FreeBSD system at school (uname -a output: FreeBSD public.ug.cs.sunysb.edu 3.2-RELEASE FreeBSD 3.2-RELEASE #1: Fri Aug 6 15:34:52 EDT 1999     root@:/A/src/sys/compile/PUBLIC  i386) gprof gives the output:

gprof: no room for 67268600 sample pc's

How-To-Repeat: Create a C program (hello.c):
int main(void){
  printf("hello world!\n);
}

Then compile it with:
$ gcc -pg -o hello hello.c

Then run:
gprof hello

Gprof seems to work OK for me on 3.4-STABLE. I'd guess you have a
gmon.out file which is corrupt or for a different type of system.
For me it produced a file called hello.gmon, so I had to give this
on the command line.

Does this problem still exist on more recent releases?
