Debugging using gdb 5.3 gives a problem "Cannot recognize signal trampoline". As a result, we absolutely cannot do any single stepping. Is this a compatibility issue ? Should I not be using gdb 5.3 with underlying linux kernel being 2.6 ? At present, we cannot upgrade to a higher version of gdb. We are compelled to use gdb 5.3 since it contains a lot of patches meant for the product. So can I apply any patch on gdb 5.3 to solve this signal trampoline problem ? I wanted to isolate and understand the problem completely and the nature of changes needed in gdb 5.3 to solve this issue. Any help here will be appreciated. I need to come to a decision regarding this issue soon since its halting the debugging for a lot of people. Thanks, Kalpana Balaji === _________________________________________________________________ Get Married in 2007. Join Shaadi.com http://www.shaadi.com/ptnr.php?ptnr=mhottag
