Bug ID: 24054
Summary: between r241513 and r241594, clang 3.7.0svn now
crashes building clang-tools-extra
Product: new-bugs
Version: trunk
Hardware: Macintosh
OS: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: new bugs

Classification: Unclassified
On x86_64-apple-darwin14 at r241513, the clang compiler from a stage1 build
successfully built clang-tools-extra as expected. At r241594, a regression is
now present where the stage 1 clang 3.7.0svn compiler now crashes in the build
of clang-tools-extra as follows...
Assertion failed: (Val && "isa<> used on a null pointer"), function doit, file
