I'm trying to build libtasn1 version 2.12, and one of the tests fails. In test_indefinite, I get:

ERROR: asn1_get_length_der overflow (l 2147483647 len 5)
version 2.11 builds without the error. Googling tells me that that function was changed between 2.11 and 2.12, but I can't follow all the details.
Mac OS X 10.7.3, clang from Xcode 4.3.1
I also run into the Apple grep bug that causes "Regular _expression_ too big" bogus messages, but I can get around that with fink's grep. The asn1_get_length_der error is the same, though.
Some possible reasons:
1. The test is using the installed libtasn1 instead of the compiled.
2. clang issue? Do you see any difference if you compile with gcc?
Turned out to be a clang issue. Adding -fwrapv to CFLAGS allowed the test to complete.
