No, Windows doesn't use ELF.
Maybe we should start by narrowing the problem? E.g., which Lisp
files cause the crashes, and which *.eln files, if any, are involved?
The C files more or less directly involved in byte-compilation are, I
think, eval.c, data.c, alloc.c, lread.c, bytecode.c. If we think one
of these could be involved, it would be nice to find the one(s) that
cause the problem, for example, by selectively compiling only those
with -fno-optimize-sibling-calls, then removing them one by one from
the set of files compiled like that.
The investigation if this bug is harder because the problem doesn't
happen when running Emacs under GDB, and conversion of backtrace
addresses to file names and line numbers for some reason also doesn't
work. So we need every smart idea we can come up with.
