Fatal error: assertion failed, file buffer.h, line 818 when fontify regex.c

Dear Developers, Does anyone of you be able to reproduce the following assert error? Fatal error: assertion failed, file buffer.h, line 818, (retval) >= ((Bytebpos) 1) && retval <= ((buf)->text->z + 0) STEPs: 1. set font-lock mode to use lazy-shot. 2. open regex.c 3. M-x font-lock-fontify-buffer Assert Error. It seems there's some thing wrong with re_match_2_internal... But I can't manage to debug it :'( back track: Thread 1 (Thread 0x7f2304781740 (LWP 28186)): #0 0x00007f23016dffb5 in raise () from /lib/libc.so.6 #1 0x00007f23016e1bc3 in abort () from /lib/libc.so.6 #2 0x00000000004d0c28 in really_abort () at emacs.c:4745 #3 0x00000000004cde7a in assert_failed (file=0x76d8f8 "buffer.h", line=818, expr=0x76d9e0 "(retval) >= ((Bytebpos) 1) && retval <= ((buf)->text->z + 0)") at emacs.c:4039 #4 0x000000000050a6a8 in BYTE_BUF_PTR_BYTE_POS (buf=0x49e2580, ptr=0x704151e <Address 0x704151e out of bounds>) at buffer.h:818 #5 0x0000000000688b42 in re_match_2_internal (bufp=0x14ebfb8, string1=0x0, size1=0, string2=0x701b9a0 <Address 0x701b9a0 out of bounds>, size2=223975, pos=154494, regs=0x14eda70, stop=223975, lispobj=77473152, lispbuf=0x49e2580, scache=0x3ae5948) at regex.c:6251 #6 0x000000000067d9a7 in sys_re_search_2 (bufp=0x14ebfb8, str1=0x520f9a0 "", size1=223975, str2=0x524cc5c "", size2=0, startpos=154494, range=69481, regs=0x14eda70, stop=223975, lispobj=77473152, lispbuf=0x49e2580, scache=0x3ae5948) at regex.c:4573 #7 0x000000000068e431 in search_buffer (buf=0x49e2580, string=76545888, charbpos=39213, buflim=223976, n=1, RE=1, trt=69193232, inverse_trt=69193232, posix=0) at search.c:1313 #8 0x000000000068dc48 in search_command (string=76545888, limit=447953, noerror=69190448, count=69193232, buffer=69193232, direction=1, RE=1, posix=0) at search.c:1164 #9 0x00000000006912e5 in Fre_search_forward (regexp=76545888, limit=447953, noerror=69190448, count=69193232, buffer=69193232) at search.c:2430 #10 0x00000000004dad01 in Ffuncall (nargs=4, args=0x7fff0c7a3698) at eval.c:3990 #11 0x0000000000477543 in execute_optimized_program ( ---Type <return> to continue, or q <return> to quit--- program=0x4919010 "\016>�\a\f\rZ\016?Y\0368\0164��a�\a�\0164!\0264 \016＠\036A\0164A\036+� \036<�\211\0362\0369�\0365\016+G\036:�\211\036; \036.�\036)\016+\203u\004\016+＠\211\026;(a)\026.\rb\210`\fW\203U\004 \016.;�\t�\016.\f�#�\005\016.\f!\203A\004`\rZ�_\f\rZ\016:_�\0165�_\016:� \\�\\\0262\0168�\021\0162\0169V�\n���\0162\016<$\210\0162\0269\016;A\211 \026)��\016)＠＠�\203�\001\016)＠＠\225\034\016)＠\211\036,＠\211\0361\224\035 \0161\225\034�\016,8\036*\016,A＠"..., stack_depth=12, constants_data=0x43b6460) at bytecode.c:898 #12 0x00000000004da723 in funcall_compiled_function (fun=62103344, nargs=3, args=0x7fff0c7a3fc0) at eval.c:3579 #13 0x00000000004dafed in Ffuncall (nargs=4, args=0x7fff0c7a3fb8) at eval.c:4035 #14 0x0000000000477543 in execute_optimized_program ( program=0x3b93060 "� �\211� �\211\031\030\036\020\036\021\036\022 \036\023�\216\v�\005�\v!\210�\r\f\"\210\016\024�\006�\r\f\"\210\016\025� \a�\r\f\n#\210�\r\f\n#.\a\207", stack_depth=6, constants_data=0x462fb50) at bytecode.c:898 #15 0x00000000004da723 in funcall_compiled_function (fun=62101040, nargs=3, args=0x7fff0c7a48b0) at eval.c:3579 #16 0x00000000004dafed in Ffuncall (nargs=4, args=0x7fff0c7a48a8) at eval.c:4035 #17 0x0000000000477543 in execute_optimized_program ( program=0x3a21b68 "\v\n\t\b#\207", stack_depth=4, constants_data=0x4a230a0) at bytecode.c:898 #18 0x00000000004da723 in funcall_compiled_function (fun=62100752, nargs=2, args=0x7fff0c7a5190) at eval.c:3579 #19 0x00000000004dafed in Ffuncall (nargs=3, args=0x7fff0c7a5188) at eval.c:4035 #20 0x0000000000477543 in execute_optimized_program ( program=0x7fff0c7a5820 "\212�ed\"\210)�\207\226�\003\225\n", stack_depth=3, constants_data=0x33be970) at bytecode.c:898 ---Type <return> to continue, or q <return> to quit--- #21 0x000000000047fffb in Fbyte_code (instructions=54258160, constants=54258016, stack_depth=7) at bytecode.c:2713 #22 0x00000000004d9674 in Feval (form=54258184) at eval.c:3738 #23 0x00000000004d5b58 in condition_case_1 (handlers=54256840, bfun=0x4d8ce6 <Feval>, barg=54258184, hfun=0x4d5c62 <run_condition_case_handlers>, harg=69193232) at eval.c:2007 #24 0x00000000004d6061 in condition_case_3 (bodyform=54258184, var=69193232, handlers=54256840) at eval.c:2089 #25 0x000000000047aa49 in execute_rare_opcode (stack_ptr=0x7fff0c7a6148, unused_program_ptr=0x3b0a70f "\210\v�\b�\030��!\210)��!�L\210\f�\f \r�\t����� $\210,��!)\207", opcode=Bcondition_case) at bytecode.c:1491 #26 0x0000000000477023 in execute_optimized_program ( program=0x3b0a6f0 "\214~\210\n\r�\002t��\034\031\035\211\033�\005��!
