Comment (by barracuda156):

 Replying to [comment:1 kencu]:
 > this looks like that same error we have been seeing for several years
 with the ODR issue with libstdc++ in libgcc on some systems.

 > The only fix for now is to use the binwrapping in legacysupport, which
 can work sometimes. Look at the cmake Portfile to see how to do it, as one
 example. In this case, looks like an intermediate build product is
 failing, and that is always harder.

 Thank you. Yes, these `malloc` errors look familiar. Usually build fails
 with them though. Here it appears to go through completion. I will see if
 there are some tests for `rakudo` to check if it works as supposed to.

 P. S. If we manage to fix `libcxx` for PPC, that will solve the problem?
 Iain said that he backported an option to use `libcxx` from `gcc12` to
 earlier versions (through `gcc10`?).
