Bug#166914: glibc 2.1 binary says: __strtoul_internal not defined in file libpthread.so.0
The problem is ages old. In the meantime we have migrated our
build environment from RH6.2 to 7.2, and the problem became
irrelevant for us. From my point of view its OK to close this
But there are still incompatibilities between glibc 2.2.4 of
RH7.2 and glibc 2.3.1-14. Our major GUI (built on RH7.2) does
a reproducable core dump when I run it on Sid. Are you interested
in another bug report?
