Bug #: 55561
Summary: TSAN crashes for Fortran
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: joost.vandevond...@mat.ethz.ch
CC: do...@gcc.gnu.org, dvyu...@gcc.gnu.org,
ja...@gcc.gnu.org, k...@gcc.gnu.org
Current trunk crashes if -fsanitize=thread is used for Fortran programs. This
is contrary to -fsanitize=address, which seems to work (PR55341). I think there
would be quite some interest in having -fsanitize=thread to work for OMP'ed
Fortran programs.
