Source: petsc Version: 3.9.0+dfsg1-1exp4 Severity: normal PETSc 3.9 Fails To Build From Source on mips. PETSC 3.8 continues to build fine.
Build logs are at https://buildd.debian.org/status/logs.php?pkg=petsc&arch=mips e.g. https://buildd.debian.org/status/fetch.php?pkg=petsc&arch=mips&ver=3.9.0%2Bdfsg1-1exp4&stamp=1524789882&raw=0 The build log reports -==== ...

Nevertheless, on amd64 the 3.9 library is 15539008 bytes, while 3.8 was 14727872, not much smaller. The amd64 3.9 debug library is 86882368 bytes where 3.8 was 84142848. On mips the 3.8 debug library is 68622188 bytes, smaller than amd64. Is this out-of-memory error a problem with the mips buildds? Are there buildd memory constraints we're hitting against? Or is there a problem with fortran95 on mips? I'm cc:ing upstream to keep them informed.
