Compilation freezing...

Question

I'm porting some old software from Solaris 2.3 to Solaris 8 with the SUNWS 5.3 Compiler. For the most part, this has been going without problems - except for two files that for some reason freeze the compiler up - i.e., the compiler simply seems to go into an unending loop on these files.
The only real similarities that I can find between the two files is that they both involve roguewave list classes - tpdlist.h - (compiled using -library=rwtool7_std); apart from this, I can't see any obvious connections.
Does anyone know what the problem might be and what might be done to solve it?

Answer 1

Are one or both of the files small enough to post? Have you attached dbx to the compiler when you think it has hung to see where the compilation gets stalled?
-- Start dbx
-- Attach to the compilation pid (you can find this with the 'top' or 'prstat' command)
-- type 'where' to see where execution has hung
% dbx
dbx> attach 16469
Reading -
Reading ld.so.1
Reading libgen.so.1
Attached to process 16469
stopped in ReportEvents at 0x10000dbd4
0x000000010000dbd4: ReportEvents+0x00a4:
dbx> where
=>[1] ReportEvents(0x100c19940, 0x10000, 0xa, ...)
In the above example, I've started dbx, attached to process 16469 and typed 'where' and dbx reports that the execution has stopped in the ReportEvents routine. Obviously, you'll get different results when attaching to the compiler.
If you can reduce the file to a manageable test case and either post it or send it to me, I can try and reproduce your problem and submit a bug report.
