Recently, when trying to use ClangBuildAnalyzer to analyze a firefox build, I got the following error and assertion failure on ClangBuildAnalyzer --stop:

ERROR: Failed to open directory (obj-x86_64-pc-linux-gnu-trace/dist/bin/chrome/en-US/locale/en-US/mozapps/downloads/settingsChange.dtd): No such file or directory.
ClangBuildAnalyzer: ../src/external/cute_files.h:427: int cf_dir_open(cf_dir_t*, const char*): Assertion `0' failed.

obj-x86_64-pc-linux-gnu-trace/dist/bin/chrome/en-US/locale/en-US/mozapps/downloads/settingsChange.dtd exists, but is a symbolic link to a file, not a directory:

This is the backtrace of the assertion failure (when I re-ran this with a debug build, it apparently hits on a different file):

This is actually a bug in cute_file.h. I filed RandyGaul/cute_headers#226 to fix it.

@sigiesec sigiesec changed the title As ../src/external/cute_files.h:427: int cf_dir_open(cf_dir_t*, const char*): Assertion `0' failed on ClangBuildAnalyzer --stop Oct 22, 2020

I've also started to encounter this issue (intermittently).

If the only issue with the pull-request was the extension length change, I'm happy to upload another pull-request if @sigiesec is no longer working on this.

@daverigby If I understand correctly, this is a problem with the file cute_files.h which is used by ClangBuildAnalyzer.
@sigiesec has already fixed this issue in upstream.
Just update this file from upstream and check if that solves the problem for you.

Upstream is located here:
https://github.com/RandyGaul/cute_headers/blob/master/cute_files.h

Can confirm that applying the upstream version of cute_files.h fixes the problem.

Would be great if this pull request could be merged so this is fixed locally.
