[Bug c/56113] out of memory when compiling a function with many goto labels (50k > )
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56113 --- Comment #32 from Kangkook 2013-04-04 18:31:19 UTC --- Hi, guys I have a couple of questions regarding the case. i) What is the current status of the fix? is this fixed or still open? ii) If it is fixed, - how many nodes now it can scale? - What version of gcc comes with the patch/fix applied? Thanks a lot for your help! /Kangkook
[Bug c/56113] New: out of memory when compiling a function with many goto labels (50k > )
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56113 Bug #: 56113 Summary: out of memory when compiling a function with many goto labels (50k > ) Classification: Unclassified Product: gcc Version: 4.6.3 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c AssignedTo: unassig...@gcc.gnu.org ReportedBy: aixe...@gmail.com Out of memory when compiling a function with many goto labels (50k > ) gcc 4.6.3 compiler(running on top of ubuntu 12.04 32-bit) failed to output an object for a function when it comes with extremely large number of goto labels. Attached is a simple script that generates the test source file. Here's how to reproduce a failure with the script. ~$./goto_gen.py 6 t.c ~$ time cc -O1 -o t t.c cc1: out of memory allocating 4064 bytes after a total of 2309808128 bytes real11m44.371s user11m42.592s sys0m1.876s ~$ time cc -O0 -o t t.c real22m5.106s user22m3.539s sys0m1.640s As you can see from the above, -O1 option trigger the problem while -O0 doesn't. Could you anyone tell me how to workaround this situation? Or which specific optimization option causes the issue? Thanks a lot for your help in advance. Regards, Kangkook

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56113 --- Comment #3 from Kangkook 2013-01-26 15:40:43 UTC --- Hi, Richard Thanks a lot for your advice. I will definitely try gcc 4.8 and let you know about the result. Btw, I also tested it from the 64-bit env. but it also crashed the compiler after using up 8GB memories. Thanks!
