https://pkg.freebsd.org/FreeBSD:15:armv7/base_latest/ has 15.snap20240726110821 and updating to it leads to avoiding the hang-up in my dlopen_test.c testing. It is based on: 126 static inline size_t 127 round_up(size_t size) 128 { 129 if (size % _thr_page_size != 0) 130 size = ((size / _thr_page_size) + 1) * 131 _thr_page_size; 132 return size; 133 } that uses the _aeabi_* routine(s) in standard armv7 builds. But that no longer causes the recursive locking deadlock problem. So, it looks like updating the kernel and world on ampere2 and enabling builds of main-armv7-default should no longer have main-armv7-default hang-up during graphviz installation (or analogous contexts). Hopefully, that means that main-armv7-default builds will then complete and be distributed. === Mark Millard marklmi at yahoo.com
