Subject: Prevent 'Unexpected heap growth' in single-threaded gctest (Linux/x64)
X-Git-Tag: v7.4.8~3
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=2b1f9641f921b7e563fbbf8019be53de4caa4d58;p=gc

Prevent 'Unexpected heap growth' in single-threaded gctest (Linux/x64)

Empirically, with incremental GC, the heap tends to grow largely as
a result of the GC not getting enough cycles.

* tests/test.c [!VERY_SMALL_CONFIG && CPP_WORDSZ==64]
(check_heap_stats): Increase max_heap_sz by ~5% (to 24M).
