Hi! Just a heads-up, I'm currently looking into the FTBFS of firebird3.0 [1] on powerpc and the backtrace seems to tell the same story:

Trying to capture what I know here. The build fails because part of the build tries to run `src/lua5.3 -v` and that segfaults. It crashes after main() exits in _IO_wsetb() in glibc's wgenops.c:105. This is because f->_wide_data points to bogus data. Setting a breakpoint in main() doesn't help because the data is already corrupted by then. Setting a breakpoint in _start or _init and then a watchpoint on this point shows that it gets corrupted in _IO_check_libio() in glibc's oldstdfiles.c. We then thought the likely culprit was compilation with g++ but linkage with gcc, however fixing that to compile and link *everything* with g++ doesn't solve the problem. This is the change we made in 5.3.1-1ubuntu1, which can be thrown away. But the problem *is* related to lua5.3's d/patches/0001-build- system.patch because if you remove that from the quilt stack, you end up with a src/lua (not version numbered) for which `lua -v` doesn't segfault. My only other thought was that maybe libtool was corrupting things, but I wasn't able to prove that. I tried various other transformations of that patch without success.
