PCH errors

PCH errors

[Richard Guenther]

Hi!

Are there known issues with the pch implementation? I get ICEs using
complex (about 45MB) precompiled headers and linker errors for smaller
(about 15MB) examples. One of the difference may be one includes some
of libstdc++, the other not (maybe).

This is g++-3.4 (GCC) 3.4 20030128 (experimental) on i386-linux,
binutils-2.10.91.0.4-40 (SuSE linux 7.2). G++ is compiled with checking
disabled.

One ICE is f.e.:

/net/bellatrix/home/rguenth/src/pooma-testsuite/r2/src/Array/tests/array_test1.cpp:174
: internal compiler error: Segmentation
   fault
Please submit a full bug report, with preprocessed source if appropriate.

The link errors look like:

/usr/bin/ld: Dwarf Error: Invalid or unhandled FORM value: 14.

Any ideas?

Should I file GNATS reports on them? The .ii files will be ridiculously
large...

Thanks, Richard.

You'd have to ask the implementers, but generally speaking the only way
that ICEs get fixed is if someone sends in a test case that the developers
can debug.

I'm not certain, but I've seen these when using a binutils version
that is too old.  What does

/usr/bin/ld --version

say?

The latter is probably a problem for such a large testcase - but maybe
geoff wants it privately.

bellatrix:~$ ld --version
GNU ld 2.10.91

So its old compared to my debian unstable version, which is 2.13.90.0.16.

If it is possible to do so, you may want to gzip or bzip the
testcase, put it on your own web site, and give out the URL to
anybody interested in investigating the testcase.
