Subject:	[geda-user] gerbv: APERTURE_PARAMETERS_MAX
From:	Sergey Alyoshin <alyoshin DOT s AT gmail DOT com>

APERTURE_PARAMETERS_MAX is defined as 102 in src/gerbv.h

I have some gerbers with more than 102 aperture parameters (175 max).  They
crash Gerbv. Is it good to increase APERTURE_PARAMETERS_MAX to say 200 or
relevant code should be rewritten with dynamic array length allocation?

At current state following patch should be applied to be able to (partially)
load gerbers with aperture parameters more than 102, report it and not crush:
