Comment 4

[Jan de Mooij [:jandem]]

Marco, is it expected that the CCov builds OOM a lot more frequently (there are some other bugs)? These tests allocate a large ArrayBuffer, do the code coverage builds do anything with malloced memory or memory mappings?

Comment 5

[Marco Castelluccio [:marco]]

The only difference I can think of with regards to memory usage is that the coverage builds need to hold coverage counters in memory.
We recently switched from GCC to Clang 11, which worsens this problem (and it will be brought back on par with GCC in Clang 12).
