Hi, I just found out that gcore has been broken with some Linux kernels for a while (observed with some 3.2 kernels on Ubuntu, but not on a vanilla 2.6.36 on another box), and this led me there: http://sourceware.org/bugzilla/show_bug.cgi?id=9904 http://sourceware.org/bugzilla/show_bug.cgi?id=11804 In particular, 11804 has an interesting discussion of the problem, and a very nice patch, which I've refreshed for gdb 7.4.1. So here it is, if anyone else needs it: it fixes gcore for my case, but I didn't check the test suite bits. It would be nice to see this finally landed in gdb!
