GDB 7.7.1 demangler crashes upon this symbol in our binary:
_ZSt7forwardIKSaINSt6thread5_ImplISt12_Bind_simpleIFZN6WIM_DL5Utils9AsyncTaskC4IMNS3_8Hardware12FpgaWatchdogEKFvvEIPS8_EEEibOT_DpOT0_EUlvE_vEEEEEESD_RNSt16remove_referenceISC_E4typeE
We have tried the patch at
https://gcc.gnu.org/ml/gcc-patches/2014-05/msg02279.html , but to no avail.

Whis works fine with binutils 2.25 and gives:

Could you try a newer version of GDB?

Thanks for the fast response, Mikhail. We use tools shipped with Yocto, so our
hands are tied to some extent. But I tried binutils 2.25 and there it works.
Thank you!
