Update: with new gdb built from source code 6631d36456babbaf4c78b955165c3344f95ac5dd at git://sourceware.org/git/binutils-gdb.git, it works.

Subject: unable to step into cxx11_tensor_shuffling via gdb




I’m using source code f3a22f35b044 from https://bitbucket.org/eigen/eigen/ with ubuntu 14.04 x64 with default compiler gcc version 4.8.4 (Ubuntu 4.8.4-2ubuntu1~14.04.3), and the build commands are:

hg clone https://bitbucket.org/eigen/eigen/

cd  eigen


make cxx11_tensor_shuffling


Under unsupported/test, I tried to run the test via gdb, but segmentation fault.

$ gdb ./cxx11_tensor_shuffling

Does anyone has the same issue and/or know how to debug it inside gdb? Thanks.


Btw, cxx11_tensor_shuffling is just an example, I also tried some other cxx11_tensor_*, they are also failed to be loaded inside gdb.
