It appears that atan2_bf() in bigflt.c isn't working correctly. This affects cmplxlog_bf() and thus ComplexPower_bf() in fractalb.c. This can be seen by starting up the manzpower fractal type and then switching to arbitrary precision math using debug=3200.
Is this executed only in Linux? The corresponding fractint code is in assembler, right? Which version has the bug? Looking at the code, it comes down to a call to unsafe_atan_bf(). We need to make a unit test and find out if the function always fails or just in certain quadrants. Tim
