Comment 2 Jakub Jelinek 2005-05-24 12:16:46 UTC
Apparently dietlibc is buggy, doesn't take into account that .eh_frame
section in more recent toolchains is read-only.
gcc's crtstuff.c from which apparently dietlibc was once copied uses
EH_FRAME_SECTION_CONST
macro for this, plus autoconf magic.
Plus you should certainly make sure dyn_start.c is compiled with -fno-exceptions,
as otherwise it is broken (otherwise __EH_FRAME_BEGIN__ very well might not be
the beginning of .eh_frame).
It is true that GCC should not ICE on any bad input, but this one is so special
case that I don't think it needs any changes.
