Assertion fails using abs()

[SiliconValley]

Loaded Beta distribution definition:

define Beta(height=1, center=0.5, fwhm=0.05) = abs(height)*exp( lgamma
((center*((center*(1-center)/fwhm^2)-1))+((1-center)*((center*(1-
center)/fwhm^2)-1)))-lgamma((center*((center*(1-center)/fwhm^2)-1)))-
lgamma(((1-center)*((center*(1-center)/fwhm^2)-1))) )*x^((center*
((center*(1-center)/fwhm^2)-1))-1)*(1-x)^(((1-center)*((center*(1-
center)/fwhm^2)-1))-1)

As soon as I add a Beta function Fityk dies with the following
assertion:

file calc.cpp
line 228
expression: 0

If I change the abs(heigth) to sqrt(heigth^2) the crash does not
happen.

Hope it helps. Ciao!

Fixed in r541.
Thanks,
