Hi dear all, I'm writing a test program to try the index API, but failed with a crash, following is the crash report: libclang: crash detected during parsing: { 'source_filename' : 'test2.c' 'command_line_args' : ['-c'], 'unsaved_files' : [('', '...', 1245120)], 'options' : 1, } Could someone help me with this ? Many thanks !
