It appears that the problem no longer happens.

After a few minutes it continues to work. See https://github.com/pkgconf/pkgconf/issues/229 pkgconf 2.0.2 landed. Does this issue still persist? The problem is resolved now that pkgconf 2.0.2 has landed. |
During a test build of devel/bear on armv7 FreeBSD 13.1 I noticed that pkg-config 1.8.0 got stuck in an endless loop in this command (processing configuration for devel/grpc 1.47.1,2): pkgconf --static --cflags-only-I protobuf grpc++ The process seems to be allocating memory every once in a while. Here is a backtrace; unfortunately I do not have debug symbols. 0x400ce0d0 in pkgconf_fragment_copy () from /usr/local/lib/libpkgconf.so.3 (gdb) backtrace #0 0x400ce0d0 in pkgconf_fragment_copy () from /usr/local/lib/libpkgconf.so.3 #1 0x400cd380 in ??
