Hi Martin

Arun told me that he will look into it - no promise though.

Hi platform-releng,
 
The equinox launcher was working fine on RHEL6 until 1 week before M7,
It fails with GLIBC_2.14 dependency since M7:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=517013
 
This is a late regression, and disappointing since I just fixed
https://bugs.eclipse.org/bugs/show_bug.cgi?id=515155
to support RHEL6. Dani asked me to send E-Mail to this list to see if
somebody can follow up.
 
It looks like recompiling the Launcher on a newer RHEL machine has caused the
Issue. So to fix it, either recompile on an older (RHEL6) machine, or apply the
changes from 515155 :
-          Add –fno-builtin-memmove to the compile command
-          Replace all occurrences of memcpy() by memmove() either in the code, or by using the preprocessor.
I thought about adding an #include “eclipse-memmove.h” to the 3 affected .c files with contents like this (pseudocode, sorry I don’t have more time now):
 
#if defined(LINUX) && defined (X86_64)
#  if defined(memcpy)
#    undef memcpy
#  endif
#  define memcpy memmove
#endif
 
That way, the impact remains limited to Linux x64 only.
 
Could somebody have a look at this please?
 
Thanks,
Martin
