Different hex files from different compiler version

Hi,

I am compiling a source code (implemented by other team in Canada) using Keil (uvision-4) V4.02, C51 (9.01), to generate the hex and map(.m51) files.

When the same source code is compiled by the Canada team from Keil (uvision-4) V4.00a, C51 (9.00), differnt hex and map file output are observed as compared to mine output.

Infact I tried download the same compiler version C51 v 9.00 (as used by the Canada Team) to generate hex and map files, but still I am getting different hex files. Could anyone comment on why I am getting different hex and map files for the same source code compiled using the same compiler?

In short, my question is, is it normal to get different hex and map files while compiling from slightly different version of the compilers (C51 v9.00 Versus C51 v9.01)? If yes then how to get around with this problem?

Will appreciate the co-operation.

Regards
Asad
