mawk @1.3.4-20171017: Fails with 'Abort trap: 6' when using binary (source okay)

Reported by: anowacki (Andy Nowacki) Owned by: tobypeterson
Priority: Normal Milestone:
Component: ports Version: 2.4.2
Keywords: Cc:
Port: mawk

Description

The binary of mawk distributed on the MacPorts servers seems to have an error:

$ sudo port install mawk && mawk 'BEGIN{print 1}'
--->  Fetching archive for mawk
--->  Attempting to fetch mawk-1.3.4-20171017_0.darwin_16.x86_64.tbz2 from http://mse.uk.packages.macports.org/sites/packages.macports.org/mawk

Running any mawk command fails in the same way.

Building from source is fine, however:

I can confirm this. Runs fine when built locally on my Mac with 10.12.6 with Xcode 9.0.1. Crashes when using the binary produced by the buildbot, which runs 10.12.6 with Xcode 8.3.3. I haven't tested other OS versions.

Relevant code hasn't changed in quite a while. I suppose the older mawk releases were built with a different Xcode version. So it's a compiler bug, I assume? The code looks fine to me.

comment:6 Changed 7 years ago by tobypeterson

I got my hands on a VM where I can repro this. Same problem occurs with mawk-1.3.4-20161120.

comment:7 Changed 7 years ago by tobypeterson

mawk is using a dynamically-sized struct (last member is str[2]), which certain older clang versions don't like. Possible fixes include converting the affected strcpy calls to use memcpy, or perhaps disabling _FORTIFY_SOURCE.

Resolution: fixed
Status: assignedclosed

Disabled _FORTIFY_SOURCE in [20d860625d3d6087809bfff4c578f70edf01a527/macports-ports].

We should undo that at some point.

Replying to tobypeterson:

Disabled _FORTIFY_SOURCE in [20d860625d3d6087809bfff4c578f70edf01a527/macports-ports].

We should undo that at some point.

Unfortunately, this has no effect on the Abort trap.
