Bug ID: 87787
Summary: [9 Regression] runtime error: null pointer passed as
argument 2, which is declared to never be null
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
CC: jwakely.gcc at gmail dot com
Target Milestone: ---
Would be also a recent regression. I see following for ubsan-bootstrapped
compiler:
$ make check RUNTESTFLAGS="gcov.exp=gcov-pr86536.c"
...
Creating 'gcov-pr86536.c.gcov'

It's about pushing a 'const char *' into a vector, I hope the usage is fine in
gcov.c. Jonathan can you please take a look?
