#1840: Reduce strain on PPC Mac OS X swapspace when test case outofmem2 fails
----------------------------+-----------------------------------------------
Reporter: thorkilnaur | Owner:
Type: bug | Status: new
Priority: normal | Milestone:
Component: Test Suite | Version: 6.8.1
Severity: normal | Keywords:
Difficulty: Unknown | Testcase: outofmem2
Architecture: Unknown | Os: Unknown
----------------------------+-----------------------------------------------
The outofmem2 test verifies that the runtime system reacts suitably to a
request to allocate an amount of memory that exceeds the available heap
space. See trac ticket #1791 for additional details.
As a practical matter, when outofmem2 fails on my PPC Mac, it does so by
succeeding to allocate about 1 Gbyte of memory. This causes a similar
amount of additional disk space worth of swapfiles to be created. And this
strains the capacity of my somewhat modest equipment.
The attached patch supplies a suggested remedy for this, by simply
reducing the amount ofmemory that outofmem2.hs attempts to allocate. It
would be very useful for me to have this patch (or any other cure of the
problem) also merged to the current stable where the problem occurs
routinely.
Best regards
Thorkil
