Reproduces the internal bug

GCC 10 just landed in Ubuntu Focal, identifying itself as

  gcc version 10.0.1 20200411 (experimental) [master revision
  bb87d5cc77d:75961caccb7:f883c46b4877f637e0fa5025b4d6b5c9040ec566]
  (Ubuntu 10-20200411-0ubuntu1)

I gave the analyzer a try and immediately hit an internal error with

  $ gcc-10 -fanalyzer -std=c99 bug.c

during IPA pass: analyzer
memory.c: In function ‘mk_entry’:
memory.c:116:12: internal compiler error: in saved_diagnostic, at
analyzer/diagnostic-manager.cc:84
  116 |     return (struct entry) {safe_calloc(end - start, 1), start, end};
      |            ^
