Subject: Successful built of 3.4.5, failing gctest from testsuite
A colleague (CC'd, not subscribed) experienced the same problem, described
in the referenced message below, with a nearly identical configuration
SUSE Linux 10.0, on i686, which only contained a prerelease of gcc-4.0.2
(20050901). He was not able to acquire ANY other release gcc version from
the SUSE package manager, which is a SERIOUS problem. He acquired the
gcc-3.4.5 and built it from 4.0.2 prelease, and experience the same
testsuite failure. Now we're suspecting possible wrong code generated by
gcc-3.4.5, possibly miscompiled by 4.0.2-pre.
Has anyone looked into this? I've seen no follow ups so far. And I
realize many are busy with 4.1.
On a side note, why does SUSE only provide one unofficial release of gcc?
I'd be VERY CONCERNED if there is no other way to get a stable compiler
built from a widely used distro (I'm not a SUSE user myself).
Regards,
David

Hi all,
here is a specification of my successful installation of gcc-3.4.5
1. Output from running srcdir/config.guess:
i686-pc-linux-gnu
2. The output of gcc -v for my newly installed gcc:
Reading specs from /usr/local/lib/gcc/i686-pc-linux-gnu/3.4.5/specs
Configured with: /local/install/gcc-3.4.5/gcc-3.4.5/configure
--program-suffix=-3.4.5 --enable-threads=posix --enable-shared
--enable-languages=c,c++,objc,f77,java --disable-checking
--enable-libgcj --enable-__cxa_atexit --with-system-zlib
--enable-java-awt=gtk
Thread model: posix
gcc version 3.4.5
3. I downloaded and enabled "c", "c++", "objc", "f77" and "java".
Firstly I tried to include "ada" as well but it failed, I had a
distribution (i.e. higher version of) "ada" installed.
4. The distribution name and version:
SUSE Linux 10.0
(this distribution includes gcc version 4.0.2 20050901 prerelease)
5. The version of the Linux kernel:
2.6.13-15.7-smp (i.e. SUSE Linux kernel)
6. The version of glibc I used:
glibc-2.3.5-40
Two additional notes:
1. I have succesfully compiled all HEASAD (LHEASOFT) package used by
astronomy community (quite substantional package) without any error.
2. Although the testsuite ran fine throughout I think almost all tests
(gcc, g77, objc, java and libraries), it finished with a following error
(WHY?):
