Description
Similar to#22104 we're seeing address conflicts loading LangInfo.dll in CI:
0 [main] perl 13868 child_info_fork::abort: address space needed by 'Langinfo.dll' (0x190000) is already occupiedCan't fork, trying again in 5 seconds at lib/MakeMaker/Test/Utils.pm line 325. 0 [main] perl 13870 child_info_fork::abort: address space needed by 'Langinfo.dll' (0x190000) is already occupiedCan't fork, trying again in 5 seconds at lib/MakeMaker/Test/Utils.pm line 325. 0 [main] perl 13872 child_info_fork::abort: address space needed by 'Langinfo.dll' (0x190000) is already occupiedCan't fork, trying again in 5 seconds at lib/MakeMaker/Test/Utils.pm line 325. 0 [main] perl 13983 child_info_fork::abort: address space needed by 'Langinfo.dll' (0x190000) is already occupiedCan't fork, trying again in 5 seconds at lib/MakeMaker/Test/Utils.pm line 325.
And rebase shows the conflict:
$ rebase -i `find . -name '*.dll'` ./perl.exe | grep -F '*'/home/tony/dev/perl/git/perl/cygperl5_41_6.dll base 0x00059f6d0000 size 0x010d8000 */home/tony/dev/perl/git/perl/lib/auto/I18N/Langinfo/Langinfo.dll base 0x00059fe80000 size 0x00025000 *
And can be similarly reproduced:
$ ./perl -Ilib -MI18N::Langinfo -efork 0 [main] perl 16510 child_info_fork::abort: address space needed by 'Langinfo.dll' (0x400000) is already occupied
I plan to prepare a fix and perldelta note PR.
Steps to Reproduce
- build perl, I've only tested with
-DDEBUGGING
, there may or may not be a conflict without it - run
./perl -Ilib -MI18N::LangInfo -efork
Expected behavior
No error on fork.
