Bug#68510: segfault in getopt (glibc)
Package: glibc
Version: 2.1.3-10
Severity: Important
all fortran programs that i've compiled (w/ Portland Group's pgf77)
segfault in the initial libc setup. same program compiled exactly the
same way on a redhat 6.1 box works, even on the Debian potato box. and
conversely, the Debian compiled version does not work on the RH box.
(though the breakage is different, but close...)
the only differences of note are:
1) Kernel Rev [2.2.14 (RH) v. 2.2.16 (D)]
2) Libc Rev [2.1.2 (RH) v. 2.1.3 (D)]
the problem seems ot be in getopt_long_only or
__getopt_clean_environment from glibc. i guess i'd have to be a borked
header or something??
