I found this bug could be occured by =sys-devel/bison-3.3.1, 
and I succeeded with =sys-devel/bison-3.2.4.

so.. I seem to find bison's bug(maybe?)

is there anyone to prove this my test?

[Comment 1 Tomáš Mózes 2019-02-01 10:55:17 UTC]

Please attach the full build log and your emerge --info, thanks.

[Comment 2 Jenny Danzmayr 2019-02-01 21:40:11 UTC]

Created attachment 563460 [details]
build.log of app-admin/syslog-ng-3.19.1 with sys-devel/bison-3.3.1

I get the same error, I attached a complete build log.

[Comment 3 PhobosK 2019-02-02 12:49:41 UTC]

I confirm this bug with the same configuration.

For some reason using python (no matter the config of python itself if 2.7 only, 3.6 only etc) breaks the compilation.

A workaround is to IUSE "-python"

[Comment 4 Tomáš Mózes 2019-02-03 04:40:48 UTC]

There is some work on this upstream (https://github.com/balabit/syslog-ng/pull/2526), but the patch does not fix the build failure, we'll have to either use <bison-3.3.1 or disable USE=python.

As agreed with Andreas, we will close this when an upstream fix is available.

[Comment 7 Tomáš Mózes 2019-02-04 11:02:20 UTC]

Please try with bison 3.3.2, it should work now.
