cannot run cargo because windows CMD error : "[0x7FFBC7A07FA4] ANOMALY: use of REX.w is meaningless (default operand size is 64)" about rust HOT 6 CLOSED

Are you on x86_64 or arm64? Those messages seem like something that an x86_64 -> arm64 translator would emit.

hi,
im on Windows X86_64.

I dont run some simulator / emulator, perhaps its coming from Antivirus which is managed by our IT admin.

Thanks.

microsoft/terminal#6391 is another report with the exact same message. There it was caused by TrendMicro. And in https://stackoverflow.com/questions/36873664/anomaly-meaningless-rex-prefix-used it was caused by a component of AMD's graphics driver.

thanks for the hints.
for the time being, can i run cargo with this error message around ?

meanwhile, i will try to follow this microsoft terminal suggestion to try our luck.

thanks.

Not easily. Whatever is emitting these messages is messing up the output of a rustc invocation that cargo parses to figure out essential information for being able to build anything at all. At best you could build your own cargo and patch it to filter out these extra messages.

understood. So i need to overcome the problem then start try again from there.

Thanks.
