Config commands:

configCmd="$srcDir/configure --enable-languages=c++\
    --disable-multilib\
    --prefix=$prefixDir\
    --disable-shared --enable-static\
    \
    --with-gmp=$prefixDir\
    --with-mpfr=$prefixDir\
    --with-mpc=$prefixDir\
    --with-isl=$prefixDir"

$configCmd                --with-boot-ldflags=" -static -static-libgcc "
|| exit 1

Both--disable-multilib and--enable-multilib give the same result.
At the end I need a 32bit-capable compiler.

I don't know how to debug the genautomata
and/or manipulate the system stack under Linux.

Maybe the stack really overflows?
