A recent series of commits to the Perl core modified the POP* macros, which are not part of the public XS API. See, for example, b405d38bc: rename POPFOO() to CX_POPFOO() Rename all the context-popping macros such as POPBLOCK and POPSUB, by giving them a CX_ prefix. (Do TOPBLOCK too). This is principally to deliberately break any existing non-core use of these non-API macros, as their behaviour has changed in this branch. In particular, POPBLOCK(cx) no longer decrements the cxt stack pointer nor sets cx; instead, cx is now expected to already point to the stack frame which POPBLOCK should process. At the same time, giving them a CX_ prefix makes it clearer that these are all part of a family of macros that manipulate the context stack. The merge commit, if you want to see the whole thing, is 9d876b687. I was able to get the test suite to run, but a number of tests still crash with either errors, or plain SIGSEGV.
Fixed in Data-Alias-1.21, just uploaded to CPAN.
