[Bug c/41567] New: Too small .bss stack

[Bug c/41567] New: Too small .bss stack

[marillat at debian dot org]

Hi,

With gcc 4.3.4 from debian unstable build with the following command line :

Configured with: ../src/configure -v --with-pkgversion='Debian 4.3.4-3'
--with-bugurl=file:///usr/share/doc/gcc-4.3/README.Bugs
--enable-languages=c,c++,fortran,objc,obj-c++ --prefix=/usr --enable-shared
--enable-multiarch --enable-linker-build-id --with-system-zlib

--enable-nls --with-gxx-include-dir=/usr/include/c++/4.3 --program-suffix=-4.3

--disable-libssp --with-system-libunwind --enable-checking=release
--build=ia64-linux-gnu --host=ia64-linux-gnu --target=ia64-linux-gnu

We are unable to build mplayer since June 2009.

The error message :

------- Comment #2 from marillat at debian dot org  2009-10-04 20:59 -------
gcc is 4.4.1 and not 4.3.4
You can find more compilation logs here (near the bottom). Click on (stderr)
link to see error messages.

http://fate.multimedia.cx/

Also mplayer doesn't build with gcc 4.1.3, 4.2.4 and 4.3.4 with the same error.

Here's additional input for this bug, focusing on the ffmpeg commit which first
triggered this error (r18553):

[Bug c/41567] Too small .bss stack

[sje at cup dot hp dot com]

------- Comment #7 from sje at cup dot hp dot com  2009-10-30 20:15 -------
I tried (and failed) to reproduce this using msmpeg4.i and compiling with:

gcc -shared -pthread -std=c99 -fomit-frame-pointer -g -O3 -fno-math-errno
-fno-signed-zeros -fPIC -fno-tree-vectorize msmpeg4.i -o x.so

I tried ToT, 4.4 and 4.3 GCC compilers and was unable to reproduce the bug.

I wonder if it only happens when linking in all the objects together.

I also wonder what linker you were using, I was using the latest 2.20 linker.

I thought the report and log was clear enough on the fact that this is
indeed a problem that only arises during the final link. If not, then
now it is ;)

[Bug c/41567] Too small .bss stack

I guess the point I was trying to make is that I don't think it is possible to
reproduce this by just compiling and linking msmpeg4.i.  I think it is
necessary to have all the objects that are being linked into the final library
in order to get the error.

I am not sure if this would help or not but it might be interesting to try the
-mno-sdata flag on the compilation to see if that helps.  By default GCC on
IA64 will use .sbss (short bss) and .bss (normal bss) sections.  -mno-sdata
will turn off the use of .sbss.

Adding -mno-sdata does not help.  Note that the error messages are always
referring to .bss, never to .sbss.

Try dropping -Bsymbolic

Removing -Bsymbolic caused many more of those messages.

[Bug c/41567] Too small .bss stack

This is a linker bug.  Recompiling without -g, so as to get error messages
without the unhelpful symbolic interpretation, I can reproduce

msmpeg4.c:(.text.unlikely+0xbe2): relocation truncated to fit: GPREL22 against
`.bss'
msmpeg4.c:(.text.unlikely+0xc80): relocation truncated to fit: GPREL22 against
`.bss'

Matching these offsets up with the object file, we see

000000000be2  000400000086 R_IA64_LTOFF22X   0000000000000000 .bss + 29658
000000000c80  000400000086 R_IA64_LTOFF22X   0000000000000000 .bss + 2a560

Notice these are *not* GPREL22 relocations, but LTOFF22X relocations.
These LTOFF22X relocations are supposed to be relaxed to GPREL22 
relocations by the linker, but ONLY IF the address is in range; otherwise
they are to be interpreted as LTOFF22 relocations which store the full
address in the GOT.

Unfortunately, the ia64 linker doesn't implement --no-relax, like other
targets do, so it's not easy to work around this bug.  Also, it would be
extremely helpful if there was a linker switch that disabled symbolic
interpretation of section+offset.  I spent a lot of time looking at the
wrong addresses...

I've created 

 http://sourceware.org/bugzilla/show_bug.cgi?id=10955

to track this problem.  You'll need to create new bugzilla accounts on
the sourceware system in order to get CC'd.

Closing this as not-a-gcc-bug.
