The version check of the dwarf compilation unit header in error_check_comp_unit_head is done too late, and consequently dwarf code with an unsupported version in the compilation unit header is interpreted as dwarf5 code in read_comp_unit_head. Fixed by moving the check earlier. Build and reg-tested on x86_64-linux. 2018-07-04 Tom de Vries <tdevries@suse.de> * dwarf2read.c (error_check_comp_unit_head): Move dwarf version check ... (read_comp_unit_head): ... here. * gdb.dwarf2/dw2-error.exp: Update expected error message.
