LKCD 4.1-1 - crash in lkcd_ksyms with PAE enabled

 

  Hi All

 

  I'm trying to use LKCD 4.1-1 with a PAE-enabled kernel, and I ran into
the following problem:

 

  After dump is saved and fetched, lkcd_ksyms always fails like this:

 

  gdb lkcd_ksyms 

 gdb> run map.1 dump.1 kerntypes.1

 

    Initializing vmdump access .Done

    Initializing system map .. Done

    Loading type info (Kerntypes)

 

   Program received signal SIGSEGV, Segmentation fault.

  0x0027273d in ?? ()

  0x0804e502 in get_next_sym_str (abfd=0x85722970, flags=140) at
lk_stabs.c:1072

  0x0804edb1 in get_next_stab_entry () at lk_stabs.c:1251

  0x0804d281 in get_stab_entries () at lk_stabs.c:419 

  ..

 

  Any ideas as to what can cause this? I am pretty sure I compiled
against proper sources so the PAE define should be on in the code.

 

  The kernel itself is RedHat Enterprise Linux 3.0 based, with lkcd
patches applied of course.

 

  Running lcrash also produces strange results, since it seems to exit
immediately after printing the "Loading type into (Kerntypes)"..

 

  If someone is willing to look into this, I'm willing to upload a
sample dump, kernel sources etc somewhere where it can be grabbed.
