H1 and L1 getting filed in same year

Employer B filed an H1B-Visa (in May 2012) for me and is under Initial Review. Now my current employer A wants to file a L1-Visa for me. Will be there be any complications in the process in US consulate or any chances that fliling of L1 may obstruct or cause rejection of my H1B visa? Please suggest…it’s urgent.
