Test case
Compile the attached file, it will require > 1GB memory and crash at some point
if it doesn't get that.
1. <eof> parser at end of file
2. Code generation
3. Running pass 'Function Pass Manager' on module 'crypt_sha512-23056a.i'.
4. Running pass 'Loop Pass Manager' on function '@php_sha512_crypt_r'
5. Running pass 'Loop Strength Reduction' on basic block '%while.body877'
Source is from current PHP, so it is high-profile.
