Bug ID: 103944
Summary: [12 Regression] Testsuite hang due to
libphobos/testsuite/libphobos.gc/forkgc2.d
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: d
Assignee: ibuclaw at gdcproject dot org
Reporter: jakub at gcc dot gnu.org
Target Milestone: ---
When trying to build gcc 12 snapshot in fedora using rpm, make check hangs, but
what is weird is that the make process has no children and is stuck waiting on
read from a jobserver file descriptor.
Strangely, during my (almost daily) normal bootstraps/regtests I'm not seeing
this.
I think I've narrowed this down to the libphobos.gc/forkgc2.d test.
When running
make -j32 -k check-target-libphobos ALT_CC_UNDER_TEST=gcc
ALT_CXX_UNDER_TEST=g++
RUNTESTFLAGS=--target_board=unix/'{,-fstack-protector-strong}'
I see it hang, again no children, but looking in detail into
libphobos/testsuite/ I see forkgc2.exe in an unfinished log there and
./forkgc2.exe process,
killing it manually make it succeed.
