Bug ID: 94328
Summary: Logging of defects to file does not work with Asan and
Ubsan combined
Product: gcc
Version: 6.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org

Source code for testcase
Compile only with the Address Sanitizer, and the resulting exe can log its
defects to file via the log_path setting in ASAN_OPTIONS
Ditto for only the Undefined Sanitizer, and using the log_path in UBSAN_OPTIONS
Combine the 2 though (the only 2 sanitizers that do seem to be allowed to
coexist) and the logging does not seem to work correctly : ASAN_OPTIONS seems
to be ignored altogether - and when I set UBSAN_OPTIONS the designated log_path
is used ONLY for the Address Sanitizer (incl LeakSanitizer) defects - the
Undefined Behavior defects go only to stderr, not to the log file.
See attached files : "test.cx" is the source, "make all" builds 3 exes, "run"
runs each, with log_path being set via the *_OPTIONS settings
Thanks for any help in addressing this.
