preamble-xxx.pch files in AppData\Local\Temp

[Tony]

Hi,

Anyone know if it's normal for preamble-xxx.pch files to accumulate in my AppData\Local\Temp directory and never get deleted?

Thank's for your help.

That is very weird. I personally haven't ever seen that before. Is preamble a project name or something related to your project? Normally the PCH files have a defined name that comes from the project file.

No this is not the name of one of my projects.
By pushing my research on google a little more I realize that I am not the only one in this case. A priori this is a clang behavior.
