Bug ID: 34638
Summary: clang crashes when building "complex" code with a
plugin
Product: clang
Version: 5.0
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org
Reporter: xaxxon at gmail.com
CC: dgregor at apple.com, llvm-bugs at lists.llvm.org
When I try to run my clang plugin on my real codebase, it crashes. I can
compile the code without the plugin and I can run the plugin on some (much)
simpler code.

I started trimming my "real" code back to try to find the problem and
eventually got found a line that when present crashed the program, but when
changed, did not (code slightly simplified from original):
float result = 3.1415926535f * 1;
If you remove the "* 1" the code compiles and my plugin works fine.
