virtual memory exhausted: Cannot allocate memory

[Mathieu Malaterre via Gcc-help <gcc-help@xxxxxxxxxxx>]

Hi all,

I am having a hard time understanding which flags to change in case of
`virtual memory exhausted: Cannot allocate memory`. I can compile
openvdb on all Debian supported arches but mipsel. I tried tweaking
the debug level as well as the optimization level without luck so far.

Latest attempt is:

g++-12 [...] -g0 -O0 --param ggc-min-expand=0 --param
ggc-min-heapsize=131072 [...]

What should I try next ?

Thanks much,
