Dear all

    Nowadays I am interested in meta-GGA DFT calculation of MoS2 materials.It needs qe package compiled with libxc.

    However after installation complete without error, testing pw.x reports following error: 

forrtl: severe (174): SIGSEGV, segmentation fault occurred

    It seems that libxcf90 were implemented in wrong way. My config.log file and installation information file "make.inc" is listed in the attachment file.

   When excluding libxc in make.inc, all the things runs normally. 

   My QE version is 6.3. with libxc version 4.2.3
