Package: gccgo-4.7
Version: 4.7.2-4
Severity: normal
Dear Maintainer,
Compiling and running the "concurrent pi" example from golang.org under
PowerPC results in the following error (cpi.go below contains concurrent pi
example code):
$ gccgo-4.7 cpi.go
~
$ ./a.out
runtime: memory allocated by OS (0x9ff57000) not in usable range
[0x2010,0xa010)
runtime: out of memory: cannot allocate 2097152-byte block (1739587584 in use)
throw: out of memory
goroutine 1 [running]:
goroutine 2 [syscall]:
no stack trace available
goroutine 3 [runnable]:
panic during panic
$ echo $?
3
This doesn't happen with the same version of gccgo under x86_64. The host has
1+ GiB RAM + 2 GiB swap (mostly free) so I don't think it's an actual memory
shortage. Nonetheless, lowering the number of spawned goroutines to 825 makes
the program run (> 825 crashes it, all regardless of free system memory).
Thanks!
