* [Bug c++/13716] New: segfaults for big functions with heaps of goto statements @ 2004-01-17 3:56 savage at light-speed dot de 2004-01-17 3:57 ` [Bug c++/13716] " savage at light-speed dot de ` (7 more replies) 0 siblings, 8 replies; 9+ messages in thread From: savage at light-speed dot de @ 2004-01-17 3:56 UTC (permalink / raw) To: gcc-bugs hey :) the following happened with 2.95.3, 2.95.4, 3.1 and 3.3 g++ segfaults when i try to compile attached file. it contains basically a single function of around 11.000 something goto statements. after some hours and consuming almost all the memory available, g++ throws the following at me: trace.cc: In function `bool invokeFunction(int, char*, RegisterFile&, float32_t**, float64_t**, float128_t**)': trace.cc:66531: internal compiler error: Segmentation Fault Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions. 3203.28u 10.18s 53:41.67 99.7% i invoked g++ with the following command line g++ -shared -O3 -funroll-loops -mcpu=v9 -mtune=ultrasparc3 -ftracer -S -o trace.s trace.cc it might be worth to mention that it also fails under plain -O2 and -O1. however, not so with -O0. here are some more invocations of g++ that might be helpful g++ -shared -O0 -S -o trace.s g++ -shared -O0 -mcpu=v9 -mtune=ultrasparc3 -S -o trace.s trace.cc g++ -shared -O0 -mcpu=v9 -mtune=ultrasparc3 -ftracer -funroll-loops -S -o trace.s trace.cc all work. g++ -shared -O1 -S -o trace.s trace.cc gives a cc1plus: out of memory allocating 3627007184 bytes after a total of 1583677440 bytes the uname -a is SunOS ulla 5.9 Generic_112233-08 sun4u sparc SUNW,Sun-Fire-480R hm. i can i attach the file? doesn't look like it... you can download it from http://savage.light-speed.de/trace.cc.bz2 hope you can fix that? (and yes, the function might look stupid, but it is generated. don't blame me ;-)) cheers, jens troeger -- Summary: segfaults for big functions with heaps of goto statements Product: gcc Version: 3.3 Status: UNCONFIRMED Severity: normal Priority: P2 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: savage at light-speed dot de CC: gcc-bugs at gcc dot gnu dot org GCC host triplet: sparc-sun-solaris2.9 GCC target triplet: sparc-sun-solaris2.9 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13716 ^ permalink raw reply [flat|nested] 9+ messages in thread
