Comment (by Martin Baute <solar@…>):

 I couldn't get gdb to produce any sensible output:

 {{{
 (gdb) bt
 #0 0x10008ec0 in ?? ()
 }}}

 Fortunately, '''dbx''' was a ''bit'' more forthcoming. Output from
 commands where it made sense:

 {{{
 Segmentation fault in . at 0x10008ec0
 0x10008ec0 (???) 93830000 stw r28,0x0(r3)
 }}}

 Other commands weren't as helpful:

 {{{
 (dbx) malloc
 libcdebug.a cannot be initialized.
 }}}

 Sorry that you have to talk me through this, but I am not familiar with
 either Boost Jam or AIX-based debugging. I'm developing on Cygwin / Linux
 mostly, then merely compile the application on Visual Studio / AIX. When
 AIX starts throwing problems at me, I feel pretty much lost. ;-)
