I just compiled and installed gdb 7.2 on my Redhat 5.x system just to get python support. I need to debug a core that was produced by (multithreaded) executable compiled and run on this system. Unfortunatelly on gdb 7.2 I get following error: (gdb) core core.5595 "/var/tmp/core.5595" is not a core dump: File format not recognized when I load the core into gdb.6.5 its format is recognized and everything works fine. Is it expected behavour, did I misconfigured something or is it a bug? best regards, Pawel
