With make -j1 everything works.

This means that for make parse_spice.lpp does not depend on parse_spice.hpp and make does not care about correct building order.

Adding explicit dependency: scan_spice.lpp: parse_spice.hpp to qucs/qucs-core/src/converter/Makefile.am fixes the problem.

The same problem with parse_vcd.hpp (it will appear at different number of parallel tasks in -j). Similar dependency is needed:

scan_spice.lpp: parse_spice.hpp
scan_vcd.lpp: parse_vcd.hpp
