Then how to use addr2line to find the root cause? please give me some
hint, thanks a lot!
$ arm-linux-gnu-addr2line -p -i -e bin/arm_armv5te/bootstrap.elf -a 00002000
Because 0001-Fix-invalid-initialization-in-new.patch has been already
merged into svn trunk, so this
http://os.inf.tu-dresden.de/pipermail/l4-hackers/2017/008111.html might
not fix my issue, but as Sarah mentioned "looks like a compiler issue"?
$ arm-linux-gnu-gcc -v
