I've already did it. It segfaults. 8-(

Moreover, Fedora 5 come with glibc 2.4.4 (not the official 2.4 release).

For a reason I don't know, the glibc installed with Fedora 5 doesn't
have this header file (jmpbuf-offsets.h). glibc 2.4 (glibc from gnu web
site has this header but not Fedora distributed glibc).

glibc versions are :

# rpm -qa|grep glibc
glibc-devel-2.4-4
glibc-kernheaders-3.0-5.2
glibc-2.4-4
glibc-common-2.4-4
glibc-headers-2.4-4

Odd thing 8-(
