Issue

Am seeing the following assembly error on CI when building for Linux ARM ( https://github.com/conda-forge/arrow-cpp-feedstock/pull/723#issuecomment-1123276844 ):

{standard input}: Assembler messages:
{standard input}:186007: Warning: end of file not at end of a line; newline inserted
{standard input}:186154: Error: unknown pseudo-op: `.alig'
aarch64-conda-linux-gnu-c++: fatal error: Killed signal terminated program cc1plus
compilation terminated.

More details in this CI log.

Would think the assembly op would be .align so this may just be a typo somewhere. Searching for similar issues seems to reveal a similar core issue (some typo somewhere). Not seeing any assembly in the source code (though could be overlooking something). Also not seeing this error in x86_64 or other builds. So wondering if this may be a compiler bug of some kind. Though could be wrong about that

Not an issue of the compiler. The compiler backend (cc1plus) got killed by a signal (maybe it was using too much memory?) and the front end (g++) passed the incomplete file to the assembler.

Good eye. Missed that. Yeah oversubscription seems like a potential cause. Will try dialing back the build threads used further. Thanks! 🙏
