A possible workaround could be to use the scan-build intercept script<br>

I am working with clang version 3.8. I have a MPI program which is causing the<br>
problem. Version 4.9.3 of mpiCC. I guess you will be able to reproduce the<br>
problem with a simple mpi program.<br>
<br>
Also, I use this compile_commands.json file:<br>
[<br>
{<br>
"directory": "~/Dropbox/CLANG_MPI_LLVM/MPI"<wbr>,<br>
"command": "mpiCC -I/usr/include/mpi BasicMPIProgram.cpp",<br>
"file": "~/Dropbox/CLANG_MPI_LLVM/MPI/<wbr>BasicMPIProgram.cpp"<br>
}<br>
]<br>
<br>
And this to run the clang tool on a mpi source file: ./tool -p<br>
~/Dropbox/CLANG_MPI_LLVM/MPI BasicMPIProgram.cpp<br>
<br>
<br>

I cannot reproduce this issue. Are you testing with ToT, or some other<br>
version of Clang?<br>
<br>

<br>
Can you give some steps to reproduce? Is it possible that the other<br>
library's API is what's causing the problem?<br>
