Some remarks, DLLs produced by cegcc have a weird IAT address because in Data Directories fields there is : Virtual Address Size 00033198 00000040 and this address doesn't even exists. On a dll produced by Visual we get : Virtual Address Size 10003000 00000024 and 10003000 corresponds to the address of .data section. Finally address are also suspicious because in old days (before all binutils hacks) sections had address like 10002000h, 10003000h,... but now it's more 00011000h, 00012000h,... Is there any reason image_base has been modified ? ------------------------------------------------------------------------------ This SF.Net email is sponsored by the Verizon Developer Community Take advantage of Verizon's best-in-class app development support A streamlined, 14 day to market process makes app distribution fast and easy Join now and get one step closer to millions of Verizon customers http://p.sf.net/sfu/verizon-dev2dev _______________________________________________ Cegcc-devel mailing list Cegcc-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/cegcc-devel
