Hi, I am trying to run guile 2.0.9 on the BlueGene Q architecture, but when I try to run the following guile script, (display "Hello, world!") (newline) the code exits immediately with the following error: *** glibc detected *** /usr/local/guile/2.0.9/bin/guile: free(): invalid next size (fast): 0x00000019c6001f00 *** I've been able to build and run it successfully on the head nodes - but when I cross compile for the compute nodes, the code dies. I've attached the config.log and the output from make and here is the backtrace /bgsys/drivers/V1R2M0/ppc64/toolchain/gnu/glibc-2.12.2/stdlib/abort.c:77 /bgsys/drivers/V1R2M0/ppc64/toolchain/gnu/glibc-2.12.2/libio/../sysdeps/unix/sysv/linux/libc_fatal.c:186 /bgsys/drivers/V1R2M0/ppc64/toolchain/gnu/glibc-2.12.2/malloc/malloc.c:6327 /bgsys/drivers/V1R2M0/ppc64/toolchain/gnu/glibc-2.12.2/malloc/malloc.c:3779 /bgsys/drivers/V1R2M0/ppc64/toolchain/gnu/glibc-2.12.2/nptl/pthread_attr_destroy.c:42 :0 :0 /usr/local/src/guile/guile-2.0.9/libguile/gc.c:653 /usr/local/src/guile/guile-2.0.9/libguile/init.c:385 /usr/local/src/guile/guile-2.0.9/libguile/threads.c:835 /usr/local/src/guile/guile-2.0.9/libguile/threads.c:901 :0 /usr/local/src/guile/guile-2.0.9/libguile/threads.c:951 /usr/local/src/guile/guile-2.0.9/libguile/threads.c:957 /usr/local/src/guile/guile-2.0.9/libguile/init.c:320 /usr/local/src/guile/guile-2.0.9/libguile/guile.c:108 /bgsys/drivers/V1R2M0/ppc64/toolchain/gnu/glibc-2.12.2/csu/../csu/libc-start.c:226 /bgsys/drivers/V1R2M0/ppc64/toolchain/gnu/glibc-2.12.2/csu/../sysdeps/unix/sysv/linux/powerpc/libc-start.c:194 ??:0
