error #10014: problem during multi-file optimization compilation (code 4)

Hi,

There seems to be an issue with multi-file optimisation (-ipo), resulting in the error:

error #10014: problem during multi-file optimization compilation (code 4)

...during the linking of the two files in the attachment, with:

icpc -Wl,--whole-archive libutil.a libgnu.a -Wl,--no-whole-archive -o liboctave.so.2.0.0

However when linking with multi-file optimisation disabled using -no-ipo flag:

icpc -Wl,--whole-archive libutil.a libgnu.a -Wl,--no-whole-archive -no-ipo -o liboctave.so.2.0.0

...the issue does not occur (the linking fails nonetheless, irrelevantly, due to missing libraries - this can be ignored).

How would one go about troubleshooting or debugging this optimisation issue? I would like to know what is going wrong here and why exactly does the optimisation fail. Is this caused by something in the .a files or is it a compiler/linker bug?

I'm currently using the following version: icpc (ICC) 14.0.2 20140120

Thanks in Advance

Cheers

Faruk
