Summary: ASTContext.cpp assertion failure
Product: clang
Version: trunk
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: Frontend
AssignedTo: unassignedclangbugs at nondot.org
ReportedBy: ejtttje at gmail.com
CC: llvmbugs at cs.uiuc.edu
Using svn-bisect, I have determined that revision 131365 introduced an
assertion which is failing on one of my Objective-C++ source files. (The
failure occurs at both that revision and through to the current trunk.) Clang
was built as Release+Asserts
You can view the file in question here:
http://cvs.tekkotsu.org/viewvc/Tekkotsu/local/DataSources/CameraSourceQTKit.mm?view=markup
I will append the assertion failure report from clang below, let me know if
there is anything else I can provide to help resolve this, thanks!
Assertion failed:
(!FieldOrBaseOffsets[layout.getVBaseClassOffsetInBits(base)]), function
getObjCEncodingForStructureImpl, file ASTContext.cpp, line 4474.
