gcc-4.6.1 compile segmentation fault

Reported by: jlhsage@… Owned by: somebody
Priority: major Milestone: 3-1-4 and higher
Component: dontKnow Version: 3-1-3
Keywords: gcc-4.6 ubuntu Cc:


On Ubuntu 11.10 alpha3, amd64, Singular-3-1-3, running 'make' causes several source files to trigger a compiler segmentation fault. When changing the compiler command line from '-O3' to '-O2', the build finished successfully.

Here is the 'make' output:

... make install in kernel make[2]: Entering directory `/home/Downloads/Singular-3-1-3/kernel' g++ -O3 -w -fomit-frame-pointer --no-rtti -pipe -fno-implicit-templates --no-exceptions -I. -I.. -I/home/jlh/Downloads/Singular-3-1-3 -I/home/jlh/Downloads/Singular-3-1-3/x86_64-Linux/include -DNDEBUG -DOM_NDEBUG -Dx86_64_Linux -DHAVE_CONFIG_H -c In function ‘BOOLEAN _ZL11smIsNegQuotP8spolyrecS0_S0_.part.12(poly, poly, poly)’: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate.

I am able to build the latest Singular (from source repository) on my ArchLinux?: Linux 2.6.39-ARCH #1 SMP x86_64 Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz GenuineIntel? GNU/Linux,

I use gcc (GCC) 4.6.1.

ps: though I didn't try to do that for 3-1-3...
