[LLVMdev] Clang: strange malloc usage
Hello everyone!
I've found weird lines of code in tools/libclang/CIndex.cpp file in clang
sources. Function clang_tokenize holds the following lines:
*Tokens = (CXToken *)malloc(sizeof(CXToken) * CXTokens.size());
memmove(*Tokens, CXTokens.data(), sizeof(CXToken) * CXTokens.size());
Since malloc function can return null pointer and there are no checks for
this case, memmove invocation leads to segmentation fault.
The same case can be found in tools/libclang/CX...

[LLVMdev] Clang
Hello everyone!
I've found strange code in tools/libclang/CIndex.cpp in function
clang_tokenize(). Lines
5570*Tokens = (CXToken *)malloc(sizeof(CXToken) * CXTokens.size());
memmove(*Tokens, CXTokens.data(), sizeof(CXToken) * CXTokens.size());
seem weird without checking the result of malloc-function invocation. Since
malloc() can return null pointer, this value can be used in memmove below.
The same case I've found...
