Hi,
I just ran into this error:
...
/home/vries/local/arm/obj/binutils-src-mainline-0-arm-none-linux-gnueabi-i686-pc-linux-gnu/binutils/dwarf.c:
In function 'process_extended_line_op':
/home/vries/local/arm/obj/binutils-src-mainline-0-arm-none-linux-gnueabi-i686-pc-linux-gnu/binutils/dwarf.c:419:38:
error: comparison between signed \
and unsigned integer expressions [-Werror=sign-compare]
...
The line referenced is:
...
6937bb54 (Nick Clifton 2014-11-18 14:40:05 +0000 419) if (len == 0 ||
data == end || len > (end - data))
...
I suspect it's due to commit 6937bb54a9c3ddc7ba330bc18af76f8dbe856ac3 (More
fixes for illegal memory accesses exposed by fuzzed binaries).
Thanks,
- Tom
