msp430-gcc fails to compile if using gcc 4.8.0, causing a segfault during compilation on a amd64. Compilation with gcc 4.7.2 works.

*** Error in `/var/tmp/portage/cross-msp430/msp430-gcc-4.6.3_p20120406/work/build/./gcc/cc1': double free or corruption (fasttop): 0x0000000000d24300 ***

Steps to reproduce:
crossdev -t msp430 -v

Still failing with gcc-4.8.2:

Just mentioning that MSP430 support was added to GCC-4.9 \o/

Has anyone tested this with gcc-4.9?  If its working there I'd really like to remove this as a blocker to 4.8.

It can. I have patches ready and waiting for building an msp430 toolchain with latest vanilla upstream gcc/binutils/newlib.

Currently it's mostly waiting for the next snapshot of binutils to fall (since it requires changes in git to build properly) or we can just take one from the toolchain overlay and stick it in the tree if necessary.

[Comment 8 Tim Harder 2014-10-31 02:44:42 UTC]

Closing as obsolete since all dev-embedded/msp430* packages are now masked. Use >=sys-devel/crossdev-20141030 to build an msp430 toolchain using the standard binutils/gcc/newlib/gdb packages.
