Comment 2 David Smith 2020-10-06 19:06:29 UTC
Since these bugs were filed against the DTS 10.0 version of GDB, I'm setting the rhdts-10.0.0? flag.

Comment 6 Frank Ch. Eigler 2020-10-22 14:32:51 UTC
It may be worth considering changing gdb itself that when forking the child process to debug, it methodically clean up -all- incoming state, including env vars, open fds, and yeah signal handlers.  It's conceivable that such litter may come in from other incidental bits of gdb environment (extension python solibs?), that a more formal hygiene pass now could prevent.

Comment 10 Martin Cermak 2020-10-26 17:40:41 UTC
Verified against devtoolset-10-gdb-9.2-8.el7 thusly:

I took the srpm, did rpmbuild -bc and then, in the testsuite dir, I did:
make check RUNTESTFLAGS='GDB=\"/opt/rh/devtoolset-10/root/usr/bin/gdb\"' TESTS=gdb.base/signals-state-child.exp

devtoolset-10-gdb-9.2-8.el7 was built using devtoolset-10-elfutils-debuginfod-client-devel-0.180-3.el7.

Reproduced and verified also with attached /tools/gdb/Regression/bz1473411-gdb-leaks-ignored-SIGPIPE-to-child-process.
