This is the continuation of bug 278895. When trying to emerge gcc, one of the processes involved deadlocks after compilation. Note that I used portage-2.1.9 which should have this issue fixed. Reproducible: Always Steps to Reproduce: 1. emerge gcc Actual Results: The process deadlocks after compilation. Expected Results: After compilation gcc should get merged.

(In reply to comment #2) > Created an attachment (id=245969) [details] > Output of ps axf This output shows that it's hung in an emake call from the src_compile function, so there's nothing portage/emerge can do about it. (In reply to comment #3) > $ lsof | grep .ipc > emerge 6055 root 3r FIFO 8,7 0t0 2113616 > /var/tmp/portage/sys-devel/gcc-4.4.3-r2/.ipc_in This is correct behavior for emerge. It should listen there until the src_compile function completes.
try FEATURES=-sandbox
Created attachment 246046 [details] Output of ps axf when emerging with FEATURES=-sandbox Same result with -sandbox
I'm unable to reproduce this with recent gcc/portage versions, closing.
