Recent versions of the Linux 32 bit LIBC library running on 64 bit machines have caused our compiler to crash with a segmentation fault. The problem started with version 2.28 of the library. You can find your version under Linux with this command:
ldd --version
Users running on a 64 bit machine who keep their Linux kernel up to date have noticed the problem. The root of the problem is when the compiler launcher (ccsc) loads the compiler dynamic library (like pcm.so) memory is corrupted. We think, but can not be sure, the newer versions of the library loader assume the code segments are aligned on 64 bit boundaries even if the library is 32 bit.
CCS has been working on a number of fronts to find a solution that will work on everyone's system. The only success we have had is to compile, the compiler to generate 64 bit code. Since this changes all our internal data types we have needed to undertake a lot of testing to ensure the compiler is sound.
The new Linux software will be available before Christmas.
This means that there will be 32 bit and 64 bit downloads for the Linux compilers. The 32 bit will work on all 32 bit systems and the older 64 bit systems. The 64 bit version will work on all 64 bit systems.
Any Linux download rights that expired in 2020 have had a year of download rights added to their account. Contact support if you need new registration files.
