Summary: Crypto++ validation test passes Panama tests at -O0
but fails at -O1, -O2, -O3
Product: clang
Version: trunk
Platform: Macintosh
OS/Version: MacOS X
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Created an attachment (id=6352)
--> (http://llvm.org/bugs/attachment.cgi?id=6352)
Replacement Makefile (uses clang instead of gcc)
To reproduce:
1) Get crypto++ from here: "svn co
https://cryptopp.svn.sourceforge.net/svnroot/cryptopp/trunk/c5 cryptopp"
2) Replace GNUMakefile with one from this bug report.
-- edit the first line of GNUMakefile to set the optimization level that you
want.
3) make test
4) ./cryptest.exe v 53 # runs just the Panama tests
If you built with -O0, the tests will succeed.
If you built with -O[123], the tests will fail.
I am working on a reduced example, but I don't have one yet.
