-* libdwarf
+   When reading (ELF_C_READ*) then there is no need to malloc Shdr
+   structure in elfXX_getshdr if file is mmaped and unaligned access
+   is allowed or the structure is aligned.  Use ELF_F_MALLOCED flag

-** Should we do more error checking?
+** shdrs after elf_cntl (ELF_C_FDREAD)
 
-   Most functions don't check whether they get a NULL value passed for
-   a pointer argument.  It could be argued that this is OK since it's
-   a bug inthe program.  But perhaps one could catch the case and return
-   an error which would allow the program using libdwarf to have fewer
-   places with error checking.
+   Similar to the above. After ELF_C_FDREAD the file is completely
+   in memory.  See also this mailing list thread:

    The old mapping should be reused in that case.  The problem is worse
