- Reply-to: gcc-bugzilla at gcc dot gnu dot org
The attached testcase needs an excessive amount of memory and compile-time to
build with -O2. 500MB max. virtual memory and 1m10s compile-time on a x86_64
machine.
The problem is inlining causes the CodeMaps::CodeMaps constructor to explode
in CFG size (also due to exception handling).
