after switching to the Intel compiler suite 2011.6 (i.e. the compiler versions 12.1) I get on some of my systems the following error at the final linker step for debug builds:
xyz.obj : fatal error LNK1318: Unexpected PDB error; RPC (23) '(0x000006BA)'
and then the linker fails.
The xyz.obj was compiled before from a F90 source using the "ifort" compiler with the "/Zi" switch amongst others. The final linking step is done by using "icl" since also other objects from C code are linked (all also compiled with "/Zi").
I found a long ago similar thing in another thread for the C compiler. - Could it be that this is related?
