------- Comment #1 from mikpe at it dot uu dot se 2010-01-24 16:04 -------
I'm now seeing failures in StackTrace2 and Throw_3 on arm-linux-gnueabi with
gcc-4.3 branch which I didn't use to see. gcc-4.4 branch doesn't fail for me on
these two, but both 4.4 and 4.3 fail (as always) on Throw_2.

------- Comment #2 from mikpe at it dot uu dot se 2010-01-25 09:33 -------
I had very recently updated binutils from 2.19.1 to 2.20 + branch updates +
some fixes from trunk. Going back to binutils 2.19.1 while changing nothing
else eliminated the StackTrace2 and Throw_3 failures from gcc-4.3.

My last gcc-4.4 build and test suite run was probably still with
binutils-2.19.1, which might explain why I didn't see those errors there.

gcc-4.4.3 with binutils-2.20 fails StackTrace2 and Throw_3, reverting to
binutils-2.19.1 eliminated those two failures.

Bootstrapping with binutils-2.19.1 but running the test suite with
binutils-2.20 did not trigger the failures. Rebuilding just libjava with
binutils-2.20 also did not trigger the failures.

Further experiments show that the failures are triggered by using the
binutils-2.20 version of ld when bootstrapping.

------- Comment #5 from mikpe at it dot uu dot se 2010-02-06 15:36 -------
Same failures when bootstrapped with binutils-2.20.51.20100202. So there's no
fix on binutils trunk to be identified and backported. I'll try to identify the
point where the regression was introduced instead.

A bisection through the binutils weekly and daily snapshots has identified
090505 as the last good snapshot and 090506 as the first bad one.

this seems to be the patch for the ARM unwind table linker processing? if yes,
see http://sourceware.org/bugzilla/show_bug.cgi?id=10695 for some comments.

I've identified <http://sourceware.org/ml/binutils-cvs/2009-05/msg00021.html>
as the source of this regression.
