Subject: [Bug sanitizer/59302] New: tsan: Unexpected mmap in InternalAllocator!
Date: Tue, 26 Nov 2013 15:33:00 -0000 [thread overview]
Message-ID: <bug-59302-4@http.gcc.gnu.org/bugzilla/> (raw)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59302
Bug ID: 59302
Summary: tsan: Unexpected mmap in InternalAllocator!
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: Joost.VandeVondele at mat dot ethz.ch
CC: dodji at gcc dot gnu.org, dvyukov at gcc dot gnu.org,
jakub at gcc dot gnu.org, kcc at gcc dot gnu.org
One tsan test I'm doing fails with:
Unexpected mmap in InternalAllocator
apart from expecting a somewhat more useful output (e.g.
Sanitizer internal error: Unexpected mmap in InternalAllocator
)
Maybe this shouldn't happen ?
I'm getting this with the following backtrace:
