[2019.1.3] Abnormal program termination (11) in ElabSvlgScope::subprogramScope()

With 2019.1.x, including 2019.1.3, I get a segfault during synthesis. The same design works fine with 2018.3.

Top of the stacktrace:

/lib64/libc.so.6(+0x3c150) [0x7fe2b9b64150]
/tools/xilinx/Vivado/2019.1/lib/lnx64.o/librdi_synth.so(ElabSvlgScope::subprogramScope() const+0x2d) [0x7fe27e9599dd]

The full stack trace is attached. It's a rather large design and I'm unable to post it fully here, we might be able to share it with Xilinx directly if that helps.

Hi

Was this ever root caused?

 

Thanks!

No. Back then the code wasn't openly available and we couldn't narrow the segfault down to a certain part of the code. The code is available now (see https://github.com/lowRISC/opentitan/issues/89), but I didn't try 2019.1 again (yet).
