Bug ID: 50037
Summary: MemorySanitizer Assertion `Size != 0 && Store !=
nullptr' failed
Product: compiler-rt
Version: unspecified
Hardware: Other
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: msan
Assignee: unassignedbugs at nondot.org
Reporter: aik at ozlabs.ru
CC: llvm-bugs at lists.llvm.org
This was from an attempt to build Linux for POWERPC64LE. clang crashes. LLVM is
upstream sha1 fbc325934661.
I am attaching the c file, it is from the kernel compiled with enabled LTO_THIN
