Description Christian Bauer 2001-03-09 20:15:38 EST
While trying to profile a C++ program that uses the CLN library with
memprof I kept getting the message "MemProf: Starter malloc exceeded
available space". I fixed this by increasing STARTER_SIZE in memintercept.c
(line 68) from 1k to 32k (to be on the safe side). I'm not exactly sure
what the STARTER_SIZE is for and why a C++ program would require a larger
value (static objects), but the default seems be too low.

We have the same problem. In it's current state, memprof is really quite
useless. Why is no updated version available???
Comment 2 Toralf 2001-06-11 12:20:59 EDT
I've now updated and built the utilitly via sources checked out from the GNOME
CVS. Note that STARTER_SIZE of 32k wasn't even enough for me, I'm now using

#define STARTER_SIZE 128*1024

It disappoints me that nobody has tried to address this issue. We are now
getting the problem once again because we have upgraded to Red Hat 7.2,
overwriting the patched version...

memprof-0.5.0-2 in Rawhide fixes this by changing the way memprof
handles intialization. I haven't seen problesm with any of the 
C++ programs I've tried.
