<pre>This assertion was reported by Benjamin Kaduk here:
<a href="http://lists.freebsd.org/pipermail/freebsd-current/2014-July/051348.html">http://lists.freebsd.org/pipermail/freebsd-current/2014-July/051348.html</a>
I reduced the test case to this very short .c file, which reproduces the
assertion with clang trunk r213143:
$ cat testcase.c
a;
GetToken() {
S1:
switch (a)
case ' ':
goto S1;
goto S1;
}
static
$ clang -v
clang version 3.5.0 (trunk 213143)
Target: x86_64-unknown-freebsd11.0
Thread model: posix
$ clang -cc1 -triple x86_64-unknown-freebsd11.0 -emit-obj -Wconsumed testcase.c
clang -cc1 -triple x86_64-unknown-freebsd11.0 -emit-obj -Wconsumed testcase.c
testcase.c:1:1: warning: type specifier missing, defaults to 'int'
a;
^
testcase.c:2:1: warning: type specifier missing, defaults to 'int'
GetToken() {
^~~~~~~~
Assertion failed: (StateMapsArray[Block->getBlockID()] && "Block has no block
info"), function borrowInfo, file
/share/dim/src/llvm/trunk/tools/clang/lib/Analysis/Consumed.cpp, line 1080.
Stack dump:
0. Program arguments:
/share/dim/llvm/213143-trunk-freebsd11-amd64-aconf-rel-2/bin/clang -cc1 -triple
x86_64-unknown-freebsd11.0 -emit-obj -Wconsumed testcase.c
1. testcase.c:9:1: current parser token 'static'
2. testcase.c:2:12: parsing function body 'GetToken'
Abort trap
Obviously, a workaround is to remove -Wconsumed, but this warning was not
explicitly enabled the original reporter; he was using -Weverything.</pre>
