I am not seeing this problem with Oracle Solaris Studio 12.4 on Solaris 10
sparc.
What compiler flags are being used on your platform? (Use "make V=1" to see.)
Can you reproduce the problem with the attached file cc-test.c, compiling with
plain 'cc -S cc-test.c'?
If so, can you send the file generated by 'cc -E cc-test.c >cc-test.i'? For
reference, the output I get with Oracle Solaris Studio 12.4 is attached as
cc-test.i. The only difference I see between 12.4 and 12.6 (the current stable
release of Solaris Studio) is in the last line, where the attached cc-test.i
says this with 12.4:
#ident "acomp: Sun C 5.13 SunOS_sparc 2014/10/20"
whereas with 12.6 it says this:
#ident "acomp: Studio 12.6 Sun C 5.15 SunOS_sparc 2017/05/30"
