Created attachment 426548 [details, diff] Patch adding --no-separate-debug-info option Upstream build system splits debug info from /usr/bin/psi into /usr/bin/psi.debug. This breaks FEATURES="splitdebug" as portage tries to split debug info from /usr/bin/psi (which is already stripped by build system at that point) into /usr/lib/debug/usr/bin/psi.debug and then strips both /usr/bin/psi and /usr/bin/psi.debug so both *.debug files doesn't contain debug symbols. ./configure has option --no-separate-debug-info which disables this unwanted behaviour. Steps to reproduce: 1. $ FEATURES="splitdebug" emerge -1 =net-im/psi-0.15 2. $ gdb /usr/bin/psi Actual results: [...] Reading symbols from /usr/bin/psi... warning: the debug information found in "/usr/bin/psi.debug" does not match "/usr/bin/psi" (CRC mismatch). warning: the debug information found in "/usr/lib64/debug//usr/bin/psi.debug" does not match "/usr/bin/psi" (CRC mismatch). (no debugging symbols found)...done. (gdb) break main Function "main" not defined. Expected results: [...] Reading symbols from /usr/bin/psi...Reading symbols from /usr/lib64/debug//usr/bin/psi.debug...done. done. (gdb) break main Breakpoint 1 at 0x4488c0: file main.cpp, line 482.

./configure has an option --no-separate-debug-info. I have no idea why it's unset for 0.15
Fixed in git commit 42f9dec3f816d75bed4b4a0421f93f00452924cd
