Reproducer #!/usr/bin/python print "int foo(void) {" print " asm(" for i in range(6400000): print r' "\n"' print " );" print "}" ./longasm.py > l.c gcc l.c Observed back to 4.7 at least, but much older compilers should be ok. So it's a regression Patch has been posted at http://www.mail-archive.com/gcc-patches@gcc.gnu.org/msg50027.html There was some discussion, but no approval
