By adding a print before the condition (line 6372), it looks that something
goes seriously wrong:
gfortran -O2:
cpu time to define wand geometries/inductances = 0.003
cpu time to define res-q coil geometry/inductances = 0.004
inductance = -4.96596104015761125E-003
inductance = -5.80817784327351903E-003
...
gfortran -O2 -ffast-math:
cpu time to define wand geometries/inductances = 0.003
cpu time to define res-q coil geometry/inductances = 0.003
inductance = -3.2565300518352496
bad mutual inductance between quad 1 and the wand transmit coil,
abort.
computed mutual inductance = -3.2565300518352496
The difference is 3 orders of magnitude!
I will run a bisection to isolate the change that introduced this failure.
