[cctbxbb] pyyaml - iotbx.pdb incompatibility

[Luc Bourhis]

Sorry James,

I hit "Send" by mistake before I was finished correcting the cut-n-paste I did from a case where I only needed to protect against divisions by zero:

The code you need is actually

try:
    division_by_zero = ext.is_division_by_zero_trapped()
    invalid = ext.is_invalid_trapped()
    overflow = ext.is_overflow_trapped()
    ext.trap_exceptions(division_by_zero=False,
                        invalid=False,
                        overflow=False)
finally:
    ext.trap_exceptions(division_by_zero=division_by_zero,
                        invalid=invalid,
                        overflow=overflow)

Best wishes,

Luc
