I hit a cryptic failure when testing a recent version of perf: # perf report write failure on standard output: Bad file descriptor
The issue is in commit b68e2f91 (perf symbols: Introduce symsrc structure). symsrc__destroy() does a close(ss->fd) but ss->fd is only initialised in the symbol-elf.c case and not for symbol-minimal.c. The issue has been around for a while however most people will build with libelf which wont use the symbol-minimal.c code.
