[odb-users] Internal Compiler Error in ODB 2.5.0-b.9 with Boost Profile

[Brian Coggins]

Hi Boris,

I’m trying to use the latest ODB (2.5.0-b.9, downloaded and built today via build2) to get c++17 support, and I’m running into that segfault people have been reporting.  Using the Boost profile seems to trigger it reliably, and the user input doesn’t seem to matter.  Here’s a test case with a completely blank user input:

$ more test.h
//      Do nothing

$ odb -d sqlite --profile boost  test.h

Back in October when this error was discussed, you asked someone on the list to include a backtrace, and you gave instructions to run with “-x -dH”.  I tried that, but it didn’t work:

$ odb -x -dH -d sqlite --profile boost  test.h

Here is the GCC version I am using to build ODB:

$ g++-8 --version
