I thought the stable version was compiled with -O which automatically
enables the omission of frame pointer usage?

hi,
I have solve the 99% CPU usage on Linux/sparc systems that
we are using, apparently changing CFLAGS from "-O2 -pipe" to
"-march=v8 -mtune=v9 -O2 -pipe -fomit-frame-pointer" cahnges
the CPU usage from 99% to max 1.8% (avg 0.4 %). So my
conclusion is this is not a dbmail bug but dbmail must trigger
some bug in platform/compiler/glibc,
Just my 2 cents
Hope this might help someone else

After more testing I have found that the important bit here is the
-fomit-frame-pointer. If I define that I don't get the excessive CPU
usage.
Is there any reason for not making this a standard compile flag?
I am running debian testing (sarge):
Which has:
gcc-3.3.1-2
kernel: 2.4.18-bf2.4 #1 Son Apr 14 09:53:28 CEST 2002 i686 GNU/Linux
libc6-2.3.2-7
mysql-client-4.0.13-3
Anything else relevant?
