I have same problem as in bug 210089, but revdep-rebuilds can not help me. From previous tests i unmerge smpeg and now revdep-rebuild try first compile smpeg again... and end with this bug again...

Check the config.log. (my guess - you need to read libxcb upgrade guide)
Created attachment 207212 [details] config.log I was upgrade libxcb according guide in eselect news. I attach to config.log, but i dont see any bad (except "configure:16286: error: *** SDL version 1.2.0 not found!" ), but i dont have any experience with reading compilations logs.
As the error is: ./configure: line 16170: 10074 Segmentation fault ./conftest$ac_exeext I'm changing my guess to: "sanitize your CFLAGS", though this may be another miss. Then again, I don't think there's a sane reason for that check to segfault.
I did test turn off all CFLAGS (except -march=pentium4 ) and is still same, not help it me :-(.
Can you post a build log from a build attempt with safe CFLAGS? If it really segfaults in the same place, then it sounds like your toolchain is sort of sick -- that is a really simple program that has no business segfaulting. If that's the case, might need to rebuild your toolchain with more conservative CFLAGS.
Created attachment 207802 [details] Config.log with minimize CFLAGS I give new log. Reduced CFLAGS="-O2 -march=pentium4", but loog look very similar.
Ok how about running that failed program under gdb to see where it segfaults. * paste the program from the log into a new file "conftest.c" * compile it using same options i486-pc-linux-gnu-gcc -o conftest -O2 -march=pentium4 -I/usr/include/SDL -D_GNU_SOURCE=1 -D_REENTRANT -Wl,-O1 conftest.c -lSDL -lpthread * run under gdb gdb ./conftest gdb> run gdb> info stack
