--- Comment #9 from Damian Kaczmarek <damian at veritymedical dot com> ---
I was dissatisfied with my DLL size being an order of magnitude bigger than it
should be and the search lead me to this bug report. I have just tried the
provided patch with binutils-2.23.2 and the initial builds of my statically
linked DLL failed with a section named "COMMON" missing. I have changed the
cofflink.c to exclude this section from removal and it finally built. However,
the functions from my DLL crash so probably something got badly removed. After
debugging the removal process by -Wl,--print-gc-sections I also prevented
.eh_frame from removal but my application still crashed. At this point I feel
only despair as COFF is basically black magic to me. Does anybody work on this
feature or have more up to date patches? I would happily do some testing and/or
help in other ways.
