Bug ID: 25990
Summary: Segfault when compiling
Product: clang
Version: 3.7
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangb...@nondot.org
Reporter: widlundtob...@gmail.com
CC: llvm-bugs@lists.llvm.org
Classification: Unclassified
Sudden segfault when compiling a previously working codebase, half way into
adding a PIMPL style wrapper, making some object types undeclared.
Below is the crash backtrace and run script:
