+There are cases, especially on PPC and MIPS, where the data address
+returned is 0, but the size is not 0.
+
+It appears to happen when the sections headers are similar to:

+  [21] .data             PROGBITS        000239c0 0139c0 000010 00  WA  0   0  8

+  [24] .bss              NOBITS          00023c18 0139e4 0001c8 00  WA  0   0  8
+  [25] .comment          PROGBITS        00000000 0139e4 000011 01  MS  0   0  1

+
+Sections 23 and 24 (.plt and .bss) which are NOBITS have a loaded data address
+of 0, but a size != 0.
+
+This could be a bug in libelf...
