Works here.  Have glibc-2.3.2-r2 though (just commited).

[Comment 2 FL 2003-05-20 14:31:31 UTC]

too an update to gcc-2.3.2-r2 won't solve the problem

[Comment 3 Martin Schlemmer (RETIRED) 2003-05-20 14:53:09 UTC]

You mean glibc right ?  Why do you say that ?  Could you maybe include a
strace of ps ?

[Comment 4 FL 2003-05-23 12:11:03 UTC]

sry. yes i meant glibc-2.3.2-r2 above. it is related to the hammer patch problem ...

Created attachment 12608 [details]
strace top

The result of "strace top".
This bug could also break mysql emerge process as I get:

bash $ emerge mysql-4.0.13
...
checking for ps... /bin/ps
checking "how to check if pid exists"... configure: error: Could not find the
right ps switches. Which OS is this ?. See the Installation chapter in the
Reference Manual.

!!! ERROR: dev-db/mysql-4.0.13 failed.
!!! Function econf, Line 304, Exitcode 1
!!! econf failed

Rebuilding procps with CFLAGS="-march=pentium3 -02 -pipe" solves the procps problem for me. (pentium3 Coppermine)

[Comment 8 Robert Moss (RETIRED) 2003-06-07 21:39:50 UTC]

The problem is the funit-at-a-time flag. Compiling with "-O3 -fno-unit-at-a-time" or with "-O2 -finline-functions -fweb -funit-at-a-time -ftracer -funswitch-loops -frename-registers" (which are effectively the same, but the second instance is less ambiguous) allows compilation and usage with no problems here.

[Comment 9 Joshua Kinard 2003-10-01 21:59:01 UTC]

Resolving as FIXED, as the last two comments provide solutions.  This is
likely to have been fixed in later versions of procps.
