tests bog down, get stuck after xfail_lexer_conflict (macOS)
snej opened this issue · comments
On my M1 MacBook Pro (16GB RAM, macOS 12.6), the tests that are run as part of ./bootstrap.sh get stuck for quite a while, at least 10 minutes, after the xfail_lexer_conflict success is logged. The entire OS gets very sluggish, and ps awx showed 300 clang processes.
The test output is:

Here’s a snapshot of top just before I killed the tests. Note that RAM is full and there is a lot of swapping.
