Bug ID: 103306
Summary: parallel build hangs since
04c5a91d068c4ca2f09c2bc206fce00db9d1790b
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Keywords: build
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: zsojka at seznam dot cz
Target Milestone: ---
Host: x86_64-pc-linux-gnu
Target: x86_64-pc-linux-gnu
Build: x86_64-pc-linux-gnu
For a few days, I am failing to build a x86_64-pc-linux-gnu compiler on one of
my systems; both bootstrap and non-bootstrap builds behave the same.
libtool: link: x86_64-pc-linux-gnu-ranlib .libs/libubsan.a
libtool: link: rm -fr .libs/libubsan.lax
libtool: link: ( cd ".libs" && rm -f "libubsan.la" && ln -s "../libubsan.la"
"libubsan.la" )

The system is 100% idle afterwards, but I don't get my terminal / build script
doesn't continue with make install.
I've bisected this to have started with
04c5a91d068c4ca2f09c2bc206fce00db9d1790b
Configure:
/repo/gcc-trunk//configure --enable-languages=c,c++
--enable-valgrind-annotations --disable-nls --enable-checking=yes,rtl,df,extra
--disable-bootstrap --with-cloog --with-ppl --with-isl

make:
make -j8
non-parallel build works fine:
make -j1
