this seems to be the issue with complex numbers referenced in issue #1

Yes this is more missing complex support (your libm.h contains some constructs). I have patches which fix this particular assertion but they are not that usefull at the moment, since codegeneration for complex is not implemented anyway.

Support for complex is implemented in cparser as of 157b9df22b3b2148603bdc63edb9d5439ed903c1. However to have it working 100% we still some change in libFirm to adhere to the gcc/ia32 calling conventions (system V doesn't seem to care about complex) where complex float is returned in 2 integer registers...

closing this issue now. The codegeneration issues for complex numbers are in a separate bug report (in the mantis bugtracker).
