[Qemu-devel] make check failed: rcutorture error

[Yijun Zhu]

Hi all,

   I got an error when doing "make check" on qemu code both stable-2.4 and 
master branch, after updating binutils to 2.24-33.

   Qemu compiled successfully with following configure command:

   $ ./configure --target-list=aarch64-softmmu 
--cross-prefix=aarch64-redhat-linux- --enable-fdt --enable-kvm

   However, it is failed when "make check", error message as below:

   ...

   GTester: last random seed: R02S413c94c1f16958c42064a5600d8f7dff
   make: *** [check-tests/rcutorture] Error 1

   And I try to get more debug info when "make check -d", it shows:

   ...

   By the way, with gcc-4.9.3 and binutils-2.23.52 it is OK. It may be 
inappropriate to put the problem here, but I really want to

   get some ideas to solve it. Thanks!
