nick, your description is correct. I have built a version of medusa using sun ld and g++, called it medusa sun, and one using g++ 4.0.2 and the latest binutil, called it medusa. readelf -h medusa > header.dump readelf -h medusa.sun > header.sun diff header.dump header.sun 11c11 < Entry point address: 0x804cb00 --- > Entry point address: 0x80d4ec0 13c13 < Start of section headers: 17001156 (bytes into file) --- > Start of section headers: 20910516 (bytes into file) 19,20c19,20 < Number of section headers: 37 < Section header string table index: 34 --- > Number of section headers: 4313 > Section header string table index: 4312 radelf -S :: a ton of diff readelf -s :: a ton of diff there are a lot of diff almost in all category. If you don't mind, I will email you the 2 image. tan --- nickc at redhat dot com <[EMAIL PROTECTED]> wrote: > > ------- Additional Comments From nickc at redhat dot > com 2006-08-08 09:54 ------- > Hi Tan, > > Sorry for taking so long to get back to this > issue. > > I am afraid I will not be able to visit you in > Santa Clara since I am > currently living in the UK...
