I got a notice from Jeff Law <law@redhat.com>:
|
|
|
04bfb0 |
|
|
|
04bfb0 |
Your particular package fails its testsuite. This was ultimately
|
|
|
04bfb0 |
tracked down to a Configure problem. The perl configure script treated
|
|
|
04bfb0 |
gcc-10 as gcc-1 and turned on -fpcc-struct-return. This is an ABI
|
|
|
04bfb0 |
changing flag and caused Perl to not be able to interact properly with
|
|
|
04bfb0 |
the dbm libraries on the system leading to a segfault.
|
|
|
04bfb0 |
|
|
|
04bfb0 |
His proposed patch corrected only this one instance of the version
|
|
|
04bfb0 |
mismatch. Reading the Configure script revealed more issues. This
|
|
|
04bfb0 |
patch fixes all of them I found.
|
|
|
04bfb0 |
|
|
|
04bfb0 |
Please note I did not test it because I don't have GCC 10 available.
