--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
I have reverted r14-11679-g8a884140c2bcb7 and this fixed the build. I can't
currently access the machine where the failed build resides, once I recover
access I'll try to gather up a non-preprocessed set of files to reproduce the
issue. I've tried N newlines before a static_assert on __LINE__ but that does
not seem to trigger it - likely some file context swaps are required.
I've tried the preprocessed source with the static_assert changed back to
__LINE__ and compiling without -fpreprocessed and that reproduces it
when compiling with -fno-preprocessed, but I'm not sure that's a valid
testcase as the #line directives in the preprocessed source are off.
In fact:
# 28
"../../../../../src/3rdparty/chromium/third_party/blink/public/common/interest_group/auction_config.h"
2
namespace blink {
is probably the first wrong line directive. The corresponding source is
#include "url/gurl.h"
#include "url/origin.h"
namespace blink {
There are larger comment blocks we skip with line directives, possibly those
are an issue as well.
For the 14 branch I think the solution is to revert the backport, the bug
was not marked as regression. I'm confirming the issue based on the
reversion fixing the build.
