- Reply-to: gcc-bugzilla at gcc dot gnu dot org
The following testcase triggers an internal error in the preprocessor
since GCC 4.2.0:
================================
#define FOO(expr) (#expr)
FOO(
#pragma GCC diagnostic
)
================================
bug.c:5:1: internal error: unspellable token PRAGMA
bug.c:5:1: internal error: unspellable token PRAGMA_EOL
bug.c:3: error: expected identifier or '(' before string constant
This is similar to PR34602, but not yet fixed on mainline.
