Description

fc-list Helvetica crashes on me with a single error line mentioning Segmentation fault: 11. Running this through gdb --args I get the following backtrace:

Program received signal EXC_BAD_ACCESS, Could not access memory.
Reason: KERN_INVALID_ADDRESS at address: 0x00000000000002b0

Trying to associate the above function list to ports installing the corresponding libraries, I obtained the following list (which might be incomplete):

The following ports are currently installed:
  fontconfig @2.11.0_0 (active)
  freetype @2.5.1_0 (active)

Originally I found this problem with graphviz dot, but this approach via fc-list should be much easier to reproduce and diagnose.

fc-list Helvetica does not crash on my system.

Crashes are usually bugs in the upstream software; please report the problem to the developers so they can look into it.
