ERROR:rbml::reader: failed to find block with tag 258 while compiling 1.2 for arm-unknown-linux-gnueabi

[Phyllostachys]

While compiling rust 1.2.0 on a Ubuntu 15.04 virtualbox VM for arm-unknown-linux-gnueabi, I ran into a panic compiling src/librbml/libs.rs at line 395.

My configuration and build commands:

./configure --target=arm-unknown-linux-gnueabi
make -j4

My rustc --version --verbose output:

rustc 1.2.0 (082e47636 2015-08-03)
binary: rustc
commit-hash: 082e4763615bdbe7b4dd3dfd6fc2210b7773edf5
commit-date: 2015-08-03
host: i686-unknown-linux-gnu
release: 1.2.0

My backtrace (with some context):

It seems that this issue has gone with the latest code

[Phyllostachys]

Excellent, I'll test to make sure next time I'm able.

[steveklabnik]

I'm going to give this a close. @Phyllostachys let me know if this still happens for you.

[Phyllostachys]

Will do, thanks.
