--- Comment #7 from glaubitz at physik dot fu-berlin.de <glaubitz at physik dot

I am still seeing this issue.

With any version of binutils 2.24.51, gcc-4.9 fails to build from source in
Debian on SH4:

> http://buildd.debian-ports.org/status/fetch.php?pkg=gcc-4.9&arch=sh4&ver=4.9.1-16&stamp=1412806436
> http://buildd.debian-ports.org/status/fetch.php?pkg=gcc-4.9&arch=sh4&ver=4.9.1-16&stamp=1412796043
> http://buildd.debian-ports.org/status/fetch.php?pkg=gcc-4.9&arch=sh4&ver=4.9.1-16&stamp=1412784287

The error is:

sh4-linux-gnu-g++   -g -DIN_GCC    -fno-exceptions -fno-rtti
-fasynchronous-unwind-tables -W -Wall -Wno-narrowing -Wwrite-strings

/usr/bin/ld: .eh_frame_hdr refers to overlapping FDEs.
/usr/bin/ld: final link failed: Bad value
collect2: error: ld returned 1 exit status

After downgrading to binutils 2.24, gcc-4.9 has been compiling fine so far and
did not fail after around 2 hours. I don't have a full build log yet since the
machine is still building, but once I do, I will provide here.

In the meantime, here's the buildlog with binutils 2.24 building a slightly
older version of gcc-4.9:

> http://buildd.debian-ports.org/status/fetch.php?pkg=gcc-4.9&arch=sh4&ver=4.9.1-4&stamp=1408496214

Any way I can help debugging the issue?

Adrian
