Comment (by wenzeslaus):

 This is probably the error message:

 {{{
 ValueError: invalid literal for int() with base 8:
 '08420217248550443400745280086994171'
 }}}

 and in context:

 I don't know how to find where this is coming from. My attempt:

 {{{
 > grep -IrnE 8420217248550443400745280086994171
 /usr/include/boost/multiprecision/cpp_dec_float.hpp:2426:
 cpp_dec_float("1.08420217248550443400745280086994171142578125000...000e-19"),
 }}}

 Since it is in multiple files and the number is not in GRASS GIS source
 code, it is coming from a library header. Indeed `0842...` is not octal.
 Do we need new ctypes or is there something strange in some header?
