Bug#947751: gcc/g++: fails to build ceph on armel/armhf/mipsel

[Bernd Zeimetz <bzed@debian.org>]

Package: gcc-9
Version: 9.2.1-21
Severity: normal

Hi,

gcc/g++ fails to build ceph on (at least) armel/armhf/mipsel.

virtual memory exhausted: Cannot allocate memory

I've played with various combinations of
--param ggc-min-expand=10 -O1 -g0

but it all did not help.
https://buildd.debian.org/status/fetch.php?pkg=ceph&arch=armel&ver=14.2.4-5&stamp=1577557420&raw=0
for example.

clang(++) seems to do better, but does not support NEON as needed to
build the jerasure code on armel.

But I still think, even with complex code like ceph, a compiler should
behave when it comes to memory usage, at least on those embedded
platforms.


Thanks,

Bernd
