Internal error

I got an “Internal error” ( no more output information ) compiling a kernel for GPU usage ( with -deviceemu compiles ok ) in both Debug and Release mode.

My command line in debug mode is:

"$(CUDA_BIN_PATH)\nvcc.exe" -ccbin "$(VCInstallDir)bin" -c -keep -use_fast_math -maxrregcount 16 -D_DEBUG -DWIN32 -Xcompiler /EHa,/W3,/nologo,/Wp64,/Od,/Zi,/RTC1,/MTd -I"$(CUDA_INC_PATH)" -o "$(PlatformName)\$(ConfigurationName)\CUDA.obj"

in Release mode is:

(CUDA_BIN_PATH)\nvcc.exe" -ccbin "(VCInstallDir)bin” -c -keep -use_fast_math -maxrregcount 16 -DNDEBUG -DWIN32 -Xcompiler /EHa,/W3,/nologo,/Wp64,/Ox,/Ob2,/Oi,/Ot,/Oy,/GT,/GL,/MTd -I"(CUDA_INC_PATH)" -o "(PlatformName)$(ConfigurationName)\CUDA.obj"

Yep, i’m using cpp integration btw.

If I remove the “-maxrregcount 16” compiles ok. With maxreg 32 fails too with “Internal error”. So I bet is some error related to the number of registers… but it doesn’t give more error information… .just a simple “Internal error”.

I would wish to keep my kernel code private unless a NVIDIA worker asks it for debugging purposes. thx.
