Hi All,

I'm trying to built  FB from the source code v. 2.5.2.26540-0 on AIX 6.1 (PPC). I've made some minor changes in the build script to let it create ./configure script, also a couple of source code files slightly changed (mostly to avoid conflicts).
But now I'm facing a problem - attempt to create/access to DB file causes core dump in Jrd::LockManager::attach_shared_file() function.
Actually, it happens during the build when empty.fdb and other DB files are created. Manually retrying create_db I can get all all .fdb files created (files are created in spite of  core dump).

AIX 6.1 PPC, XL C++ compiler

My settings:

this is the core stack of create_db:

(gdb) where
#0  0x000000010037945c in Jrd::LockManager::attach_shared_file( (long *)) (this=0x700000000006fa0,

#5  0x0000000100001338 in main (argc=2, argv=0xffffffffffff910) at ../src/utilities/create_db.cpp:49

Any ideas what should I do to make it working would be appreciated.

Thanks.
