Bug 182374 – [ICE/4.1/4.2] building CAPS Audio Plugin Suite causes gcc to ICE

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Dominique Michel 2007-06-17 18:47:14 UTC]

I downloaded the source for the CAPS audio plugins from http://quitte.de/dsp/caps.html and try to install it by hand before to do an ebuild.

During compilation, I get a gcc internal error and segfault.


Reproducible: Always

Steps to Reproduce:
1. download http://quitte.de/dsp/caps_0.4.0.tar.gz
2. untar it
3. ./configure.py
4. make


Actual Results:  
g++ -O3 -ffast-math -funroll-loops -Wall -fPIC -DPIC -msse -mfpmath=sse -I/usr/local/include -c ToneStack.cc
Descriptor.h: In static member function ‘static void Descriptor<T>::_run_adding(void*, ulong) [with T = ToneStackLT]’:
Descriptor.h:209: erreur interne du compilateur: Erreur de segmentation
// Mean "Compilator internal error: segfault
Veuillez soumettre un rapport complet d'anomalies,
avec le source pré-traité si nécessaire.

Expected Results:  
At those plugins did compile.

The preprocessed sources is too big for bugzilla, so here it is: http://www.alsaplayer.org/tmp/ccebPbaG.out

We don't support stuff that's not in the tree.

[Comment 4 Dominique Michel 2007-06-17 20:35:47 UTC]

I know that, but the segfault is not when running this audio plugin but with gcc. And gcc is in the tree.

Mo matter, i will commit this bug upstream.

[Comment 5 Dominique Michel 2007-06-17 20:50:57 UTC]

BTW, I get this plugion to compile be removing -funroll-loops from the cflags in the Makefile.

[Comment 6 Harald van Dijk (RETIRED) 2007-06-18 00:37:32 UTC]

You're right, gcc bugs should be filed here.

Reduced testcase:

double f1();
int f2() {
  __builtin_ia32_stmxcsr();
  return f1();
}

$ i686-pc-linux-gnu-gcc -msse -c bug.c
bug.c: In function ‘f2’:
bug.c:5: error: insn does not satisfy its constraints:

gcc-4.1.1 is old, gcc-4.1.2 is stable now

upgrade to that and if it still ICEs, then try with LC_ALL=C and post your results

[Comment 9 SpanKY 2007-06-18 00:52:23 UTC]

ah Harald posted a reduced test case ... this still ICEs on gcc-4.2

added the fix from upstream to our gcc patchsets ... it'll be fixed in next release
