not expected behavior when using sym resolver #581
Description
environment:
Python 3.11.8 (tags/v3.11.8:db85d51, Feb 6 2024, 22:03:32) [MSC v.1937 64 bit (AMD64)] on win32
keystone-engine 0.9.2 (from pip)
reproduce code:
import capstone
import keystone
def main():
ks = keystone.Ks(keystone.KS_ARCH_X86, keystone.KS_MODE_64)
cs = capstone.Cs(capstone.CS_ARCH_X86, capstone.CS_MODE_64)
def resolver(key, p_value):
if key == b'func_':
p_value[0] = 0x9
return True
return False
ks.sym_resolver = resolver
code_1 = 'lea rax, [rip + func];call rax;func:mov al,1;ret;'
code_2 = 'lea rax, [rip + func_];call rax;func:mov al,1;ret;'
for i in cs.disasm(ks.asm(code_1, 0, True)[0], 0): print(f'{i.address:X}: {i.mnemonic} {i.op_str}')
print('---')
for i in cs.disasm(ks.asm(code_2, 0, True)[0], 0): print(f'{i.address:X}: {i.mnemonic} {i.op_str}')
if __name__ == '__main__':
main()expected ouptut:
0: lea rax, [rip + 2]
7: call rax
9: mov al, 1
B: ret
---
0: lea rax, [rip + 2]
7: call rax
9: mov al, 1
B: ret
actual output:
0: lea rax, [rip + 2]
7: call rax
9: mov al, 1
B: ret
---
0: lea rax, [rip + 6] << here
7: call rax
9: mov al, 1
B: ret
