Userland programs segfault. Basically you get an unusable system at boot time.

Hi,
The defect: from 4.14 on, ccache in its default direct mode looks for
.incbin only in the raw source text, and only before a literal quote.
vdso_wrap.S names the file through a macro (VDSO_FILE), so the check misses
it. In direct mode the preprocessed text, where the name would be visible,
is no longer scanned.
When it hits: when the vDSO changes.
The workaround: use CCACHE_NODIRECT=1
Hi Alexander,
What’s the net-effect of this issue? Is it a functional problem? Is it a
security problem? Etc. Is there a bug tracking this issue on Bugzilla?
Thank you,
