Sounds like it worked too well!  ;-)

No, seriously, I don't think COFF supports --gc-sections at all.

Actually, ld.info says this (but I presume they mean MS COFF, primarily):

"
Note that garbage collection for COFF and PE format targets is supported,
but the implementation is currently considered to be experimental.
"

It probably shouldn't crash, but it's probably also not really supported
for us.
