Description

On machines with 8GB of physical memory in the openSUSE Build Service, attempts to build infernalis are prematurely cut off by cc1plus: out of memory allocating 4194304 bytes after a total of 31973376 bytes.

This is because gcc's default values of ggc-min-expand and ggc-min-heapsize cause it to collect garbage too aggressively on these machines.

Thanks to my colleague Berthold Gunreben for debugging this issue.
