|Summary||0000053: Linking problems in otherlibs/str|
|Description||Full_Name: Gerd Stolpmann|
Version: 2.04/Current CVS version
Submission from: master.proxy.ision.net (188.8.131.52)
I recently detected a problem with otherlibs/str. The GNU regex library defines
the function regfree, which is a POSIX.2 function. Under Solaris, I observed
that the call of regfree in strstubs.c actually invoked the regfree function
defined in libc, and not the regfree function defined in regex. This caused
a core dump every time a regexp value was finalized.
Fortunately, regfree is the only regexp function which conflicts with POSIX
functions; the other calls of regexp functions are not affected.
I have a patch which avoids to call regfree at all (by simply copying the
invocations into the stub function):

Well spotted. I fixed this by renaming regfree in the GNU regex library,
and #ifdef'ing away all POSIX and BSD emulation code in that library
(we don't need it).
Thanks for the bug report,
