Package: src:mlton
Version: 20180207-1
Severity: serious
Justification: fails to build from source (but built successfully in the past)
Hi!
I've been doing a full rebuild of the Debian archive, building all
source packages targeting armel and armhf using arm64 hardware. We are
planning in future to move all of our 32-bit armel/armhf builds to
using arm64 machines, so this rebuild is to identify packages that
might have problems with this configuration.
I found that mlton is failing with segfaults in its test suite.
Looking further, I can see that the same problem is showing up on our
buildds for at least arm64 and armel too. I was going to try and debug
the problem:
...
testing world6
1,4c1
< ./world6
< a
< b
< c
---
> Segmentation fault (core dumped)
...
(sid-armel)steve@mjolnir:~/debian/build/mlton/mlton-20180207$ find . -name core
./regression/core
(sid-armel)steve@mjolnir:~/debian/build/mlton/mlton-20180207$ file
regression/core
regression/core: ELF 32-bit LSB core file, ARM, version 1 (SYSV), SVR4-style,
from './world6 @MLton load-world /tmp/worldW1WpTw -- a b c', real uid: 1000,
effective uid: 1000, real gid: 1000, effective gid: 1000, execfn: './world6',
platform: 'v8l'
But it appears that the test suite helpfully carries on after crashes
and even deletes the binaries it's made:
(sid-armel)steve@mjolnir:~/debian/build/mlton/mlton-20180207$ find . -name
world6
(sid-armel)steve@mjolnir:~/debian/build/mlton/mlton-20180207$
So I'm stopping here.
