Today I'm not able to compile the current master 6f98a0fac33db70b3ceb71d939b0a9d0d47747cc.

Using git bisect I've found that the culprit seems to be this commit 

commit 59816ef00c6dd09532d80b393ba03f8194aba236

    Make the Flex scanners and YACC parser in libraries reentrant.

But how did the buildbot let it pass? Anyone experiencing the same issue?
Unfortunately I'm not goot with flex so I can't try to fix it myself.
Bye
Dario.
