[Bug bootstrap/41245] New: [4.5 Regression] Bootstrap broken on I386-apple-darwin9 at revision 151373

[fxcoudert at gcc dot gnu dot org]

Subject says it all; i386-apple-darwin is a primary platform.

Comparing stages 2 and 3
warning: gcc/cc1-checksum.o differs
Bootstrap comparison failure!
gcc/tree.o differs

The output of "../trunk/contrib/compare-debug --preserve stage[23]-gcc/tree.o"
is long, so I'll attach it, but the end of it says:

stage2-gcc/tree.o.stripped stage3-gcc/tree.o.stripped differ: char 529, line 4
stripping off .eh_frame, then retrying
failed to strip off .eh_frame
stage2-gcc/tree.o.stripped stage3-gcc/tree.o.stripped differ: char 529, line 4
preserving stage2-gcc/tree.o.stripped stage3-gcc/tree.o.stripped


I also did a dwarfdump of both stripped files, and the difference between those
two is minimal:

So I guess this should be easier to understand than the corresponding powerpc
issue (41224).
