Crash in ItemRepository

[Cédric PASTEUR]

Hi,I have more info about the crash I reported yesterday:

<unknown program name>(21398)/
KDevelop::allocateGlobalItemRepositoryRegistry: testing
"/Users/ccpasteur/.kdevduchain/0"
<unknown program name>(21398)/
KDevelop::allocateGlobalItemRepositoryRegistry: picked duchain directory
"/Users/ccpasteur/.kdevduchain/0"
<unknown program name>(21398)/ KDevelop::ItemRepositoryRegistry::open:
"/Users/ccpasteur/.kdevduchain/0/version_42" not found, seems to be an old
version
<unknown program name>(21398)/ KDevelop::ItemRepositoryRegistry::open: "The
data-repository at /Users/ccpasteur/.kdevduchain/0 has to be cleared. Either
the disk format has changed, or KDevelop crashed while writing the
repository"

Program received signal EXC_BAD_ACCESS, Could not access memory.

It seems that the ItemRepositoryRegistry& m_registry is unitialized at the
point the createRepository method is called. Maybe it's related to the order
of initialization of static objects as I've seen there was a comment about
it in the file that could explain.

Best regards
