Hello All, I've recently solved a membrane protein structure largely with the help of phenix refine. I also have been using the autobuild programs recently for ligand fitting and whatnot. The program during this time has been running flawlessly on my machine (Ubuntu 9.04 E8400 3.0ghz etc etc) However this weekend Autobuild and AutoMR spontaneously started throwing this error. (boost_adaptbx_segmentation_fault_backtrace+0x1f) [0xb7de2e27] Segmentation fault (Python and libc call stacks above) This crash may be due to a problem in any imported Python module, including modules which are not part of the cctbx project. To disable the traps leading to this message, define these environment variables (e.g. assign the value 1): BOOST_ADAPTBX_FPE_DEFAULT BOOST_ADAPTBX_SIGNALS_DEFAULT This will NOT solve the problem, just mask it, but may allow you to proceed in case it is not critical. Memtest 86 says my RAM is good. I have reinstalled phenix and am still getting the same error. I can't seem to find any other information on this error (segmentation faults are tricky I know) and am just wondering if anyone else has seen or solved this type of problem, thanks for your help.
