a 32bit executable generated with cygwin on Windows XP

Hi,


I have a 32 bit executable generated with cywin on WindowsXP (with gcc 4.3.4).
I had a look on the way CygwinPEBinaryObject loads symbols of this binary file, and found some strange things.

For example, according to CygwinPEBinaryObject, symbol "_mainCRTStartup" is located at address "0x400200".

However, the cygwin binutils do not give the same result:
$ nm a.exe | grep _mainCRTStartup
00401000 T _mainCRTStartup


Do I miss something ?

In other words, there is an offset of 0xe00 between symbol addresses given by "nm" and symbol addresses given by CygwinPEBinaryObject

I quickly debugged this with CDT 7.0.2 and for me the CygwinPEBinaryObject assigns a value of 4198400 (0x401000) for _mainCRTStartup.

Hi,

I investigate deeper on that, and I found that this bug has been fixed by revision 1.27 of org.eclipse.cdt.utils.coff.PE.

So it's fixed in CDT 7.0

I mark the bug a closed/fixed.
