Fixing patch
This patch should solve the problem.
Please run some test with it applied, if you can.
The test case now passes. Thank you for fixing it, Luca! A commit references this bug: Author: tijl Date: Sun Oct 18 17:31:17 UTC 2015 New revision: 399623 URL: https://svnweb.freebsd.org/changeset/ports/399623 Log: Fix a regression when debugging a threaded process that forks. PR: 203661 Submitted by: luca.pizzamiglio@gmail.com (maintainer) Changes: head/devel/gdb/Makefile head/devel/gdb/files/fbsd-threads.c *** Bug 203770 has been marked as a duplicate of this bug. *** For whatever reason I see the same problem again with the current gdb. I am not sure how is this possible that this test passed when you asked me to test it on 2015-10-16. But now I have exactly the same symptom again. Hi Yuri, unfortunately, I'm not able to reproduce the error anymore... please, re-check that your devel/gdb/file/fbsd-thread.c has the patch attached in this bug report. Could you also provide the output of make showconfig? HI Luca, I verified that all patches are in sync with subversion repository, rebuilt gdb, and still see this problem. OS version: 10.2-STABLE #0 r290123: Wed Oct 28 17:59:42 PDT 2015 amd64 Possibly not the same bug, but the same error message.
Linking with pthreads and openmp. Using popen(), gdb emits this error during the call to popen(). If I then 'q'uit gdb, the program is detached and runs to completion. I am unable to 'c'ontinue execution in the debugger.
I'm up to date with the patches, 10.1-RELEASE, compiled with g++48.
/usr/ports/devel/gdb# make showconfig
===> The following configuration options are available for gdb-7.10_3:
DEBUG=off: Build with debugging support
EXPAT=off: XML parser support via Expat
GDB_LINK=on: Create /usr/local/bin/gdb symlink
GUILE=off: Guile extension language support
KGDB=on: Kernel Debugging Support
PYTHON=off: Python bindings or support
THREADS=on: Threading support
TUI=on: Text User Interface enabled
====> Command line editing via libreadline: you have to select exactly one of them
BASE_READLINE=off: from base system (experimental)
BUNDLED_READLINE=off: from gdb distfile
PORT_READLINE=on: from devel/readline port

Fixing that bug and a potential build issue
I've build a test case with popen() and then I was able to reproduce the error.
This patch should fix the problem.
Moreover, this patch fix a potential parallel build issue.
