Bug ID: 22317
Summary: clang 3.5 crashes in clang::TryImplicitConversion
Product: clang
Version: 3.5
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org
Reporter: floooh at gmail.com
CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
Classification: Unclassified
Since emscripten switched to clang 3.5 from 3.4 I'm getting intermittent
crashes when compiling a specific C++ file, the crash seems to happen much more
often when running make with more then 3 or 4 build jobs.
Console output with callstack (also see the 2 attached files)
