I tried
configure --enable-64-bit-bfd --enable-largefile
And gdb still has problems accessing memory in the KDUMP that the crash-utility can
read.
For example crash can walk the task list but when the gdb macro tries
To access the memory of the second task gdb says it can't access memory.
Hi.
It's not clear from the description that this is a largefile problem.
As an experiment, what happens if you build with CFLAGS="-g -O2
-D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE" ?
[not all of these macros may be necessary, configure should be
defining _FILE_OFFSETS_BITS=64, THIS IS JUST AN EXPERIMENT]

This was:
https://bugzilla.redhat.com/show_bug.cgi?id=457187
Nowadays it is only enough to use during configure:
--enable-64-bit-bfd
Additionally Fedora is carrying for Linux kernel support:
