Hi,

I'm the same person asking about compiling from CVS earlier today (get back
to that later). For now, I just downloaded curl-7.10.2-pre1 and compiled
it. I compiled like so:

$ CFLAGS="-g -O2 -march=i686" ./configure --enable-debug
$ make
$ make install

Recompiled my program using the curl_memdebug call. I found that the
library installed with make install did not include this call so I linked
my program against memdebug.o from the curl source tree. Is this correct?

After running my program, I analyzed the dump and here is the beginning
(too big to send to list):

It looks like some of the lines got corrupted. Maybe is writing to this
file not serialized? My program is multithreaded.
