Benoit Dolez reported a failure to start haproxy 1.5-dev19. The process would immediately report an internal error with missing fetches from some crap instead of ACL names. The cause is that some versions of gcc seem to trim static structs containing a variable array when moving them to BSS, and only keep the fixed size, which is just a list head for all ACL and sample fetch keywords. This was confirmed at least with gcc 3.4.6. And we can't move these structs to const because they contain a list element which is needed to link all of them together during the parsing. The bug indeed appeared with 1.5-dev19 because it's the first one to have some empty ACL keyword lists. One solution is to impose -fno-zero-initialized-in-bss to everyone but this is not really nice. Another solution consists in ensuring the struct is never empty so that it does not move there. The easy solution consists in having a non-null list head since it's not yet initialized. A new "ILH" list head type was thus created for this purpose : create an Initialized List Head so that gcc cannot move the struct to BSS. This fixes the issue for this version of gcc and does not create any burden for the declarations. |
