Bug #: 56510
Summary: adding -g compiles 'forever' vs 49s
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: sam-gcc...@rushing.nightmare.com

repro
The file is output from another compiler, in CPS form (i.e., all funs are tail
calls).
If I leave off '-g' it takes 49 seconds to compile (2.4GHz core i7)
If I add '-g' it takes 'forever' (> 90 mins).
Reproduced on OS X (10.8.2) x86_64, Linux Ubuntu (w/gcc4.6.3), FreeBSD 7.3.
I believe this bug affects gcc going back to 4.6 and earlier. I have a copy of
4.2 sitting around that does not seem to have the problem, though.
gcc was configured: "./configure --enable-languages=c,c++"
built with "make -j 16"
command: /usr/local/bin/gcc -std=c99 -O3 -g -I./include self/compile.c -o
self/compile
