sources (libclangclient.cpp) and test input to reproduce the problem
Compile the attached libclangclient.cpp in debug mode.
Then run the executable:
<span class="quote">> set LIBCLANG_TIMING=1
> libclangclient.exe /path/to/main.cpp</span >
file path: D:\work\libclang38winMultiplePreambleGenerations\testsource\main.cpp
Parsing D:\work\libclang38winMultiplePreambleGenerations\testsource\main.cpp:
-----
Precompiling preamble: 0.0156 (100.0%) 0.0156 (100.0%) 0.0156 (100.0%)
Reparsing D:\work\libclang38winMultiplePreambleGenerations\testsource\main.cpp:

Precompiling preamble: -----
Reparsing D:\work\libclang38winMultiplePreambleGenerations\testsource\main.cpp:
0.0156 (100.0%)
Note that the preamble is not only generated for the first reparse, but also
for the second.
This does not happen on Linux, there it's only generated for the very first
reparse.</pre>
