Description Dmitry V. Levin 2000-10-28 23:26:44 UTC

$ cpp -A blabla </dev/null
cpp: Internal error: Segmentation fault (program cpp0)

Problem in gcc/cpplib.c, function do_assert,
dereferencing null pointer.

Bug still exists in current CVS tree.
I'm not gcc hacker, so reporting here.

Comment 1 Jakub Jelinek 2000-10-30 15:47:06 UTC

Actually, it seems this segfault went away in CVS with 2000-10-28
CPP lexer rewrite.
As I don't trust that shiny new lever yet though, I wrote a fix for this
for the old lexer and will be testing it with other changes in gcc-2.96-62.
