Bug 687492 – dev-lang/go-1.12.5 on 32-bit system results in perpetual revdep-rebuild

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description solamour 2019-06-06 04:57:16 UTC]

After installing "dev-lang/go-1.12.5" on an x86 machine (i.e. 32-bit), "revdep-rebuild" wants to keep rebuilding "dev-lang/go".

Reproducible: Always

Steps to Reproduce:
1. Install "dev-lang/go-1.12.5" on an x86 machine (i.e. 32-bit).
2. Run "revdep-rebuild", which will rebuild "dev-lang/go".
3. After rebuilding "dev-lang/go" is done, run "revdep-rebuild" again.
Actual Results:  
"revdep-rebuild" will rebuild "dev-lang/go" again, even though it just finished rebuilding.

Expected Results:  
Once rebuilding "dev-lang/go" is done, it should stop rebuilding.

"revdep-rebuild -p -d" shows the following.

   * Broken files that require: libc.so.6 (64 bits)
   * /usr/lib/go/src/cmd/vendor/github.com/google/pprof/internal/binutils/testdata/exe_linux_64
   * /usr/lib/go/src/debug/dwarf/testdata/ranges.elf
   * /usr/lib/go/src/debug/dwarf/testdata/typedef.elf 

Those files are 64-bit executables, so they shouldn't be in a 32-bit machine. But they are, so "revdep-rebuild" wants to rebuild, which doesn't solve the problem.

If I remove aforementioned files, "revdep-rebuild" finally says the system is consistent.

Can confirm this also happens on arm.

Confirm. The same on x86. go-1.12.9 keeps rebuilding every time.

The same on my Gentoo i686 also, dev-lang/go-1.12.13.

    dev-lang/go: 1.14.2 bump
    
    I am also removing the "testdata" directories from the installation and
    enabling tests since they work on amd64.

Is there a possibility that we could get this backported to the stable versions?  Every time I run revdep-rebuild on my stable system it rebuilds.
