Bug ID: 94191
Summary: ubsan bootstrap memory hog with -enable-checking=rtl
Product: gcc
Version: 9.3.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: zhroma at gcc dot gnu.org

Target Milestone: ---
On 64Gb RAM x86_64 box using 9.3 sources and running:
<src>/configure --enable-languages=c,c++ --with-build-config=bootstrap-ubsan
--enable-checking=rtl; make
During stage2 insn-extract.c compilation was stopped by OOM killer. It really
wants 60+ Gb of memory.

Yeah, it's a bit crazy checking options and not sure we have to bother about
it.
