Bug ID: 123770
Summary: [16 Regression] Memory bloat seen when running
-fanalyzer integration tests
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Keywords: memory-hog
Severity: normal
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: dmalcolm at gcc dot gnu.org
Target Milestone: ---
I recently noticed that the memory usage of the analyzer integration tests has
regressed, in that my test runs are driving my testing machine deep into swap
and rendering it unresponsive. That said, the runs do eventually complete,
apparently successfully.
I see it with 3119cfc9118eb8545dac9bf765c93f762ad8794a, aka
r16-6781-g3119cfc9118eb8, but I'm not sure exactly when this behavior started.
I suspect I may have introduced it with the supergraph rewrite of
r16-6063-g0b786d961d4426 (leading to much larger exploded graph representations
in memory), but I don't know yet.
Filing this to have a place to track further investigation.
