# When running Debian's Xwayland and fontconfig, we hit memory leaks which |

# aren't visible on other setups. We do have suppressions for these tests, but |
||||
# regrettably ASan can't see through omitted frame pointers in Expat, so for |
||||
# Xwayland specifically, we disable fast-unwind. |
||||
# |

# Doing it globally makes the other tests far, far, too slow to run. |
