Bug 18763 – Segfault in garbage collector

This program gives a segfault somewhere in the garbage collector when ran with oscillofun.flac as input.

You forgot to upload an attachment apparently. SEGFAULT by GC can be caused by a destructor that allocates. destructor are not allowed to.

Created attachment 1685 Test case for segfault Added test case (as seen on IRC). Stacktrace (also as seen on IRC): Program received signal SIGSEGV, Segmentation fault. 0x00005555555d5b35 in _D2gc4impl12conservativeQw3Gcx11fullcollectMFNbbZm () (gdb) bt #0 0x00005555555d5b35 in _D2gc4impl12conservativeQw3Gcx11fullcollectMFNbbZm () #1 0x00005555555d8856 in _D2gc4impl12conservativeQw14ConservativeGC__T9runLockedS_DQCeQCeQCcQCnQBs18fullCollectNoStackMFNbZ2goFNbPSQEaQEaQDyQEj3GcxZmTQvZQDfMFNbKQBgZm () #2 0x00005555555d2961 in _D2gc4impl12conservativeQw14ConservativeGC18fullCollectNoStackMFNbZv () #3 0x00005555555d2932 in _D2gc4impl12conservativeQw14ConservativeGC14collectNoStackMFNbZv () #4 0x00005555555e5cf1 in gc_term () #5 0x00005555555da3cb in rt_term () #6 0x00005555555c63b5 in rt.dmain2._d_run_main(int, char**, extern(C) int(char[][]) function).runAll() () #7 0x00005555555c6290 in rt.dmain2._d_run_main(int, char**, extern(C) int(char[][]) function).tryExec(scope void() delegate) () #8 0x00005555555c61fb in _d_run_main () #9 0x00005555555bbede in main () #10 0x00007ffff6bf2a87 in __libc_start_main (main=0x5555555bbebc <main>, argc=2, argv=0x7fffffffea68, init=<optimized out>, fini=<optimized out>, rtld_fini=<optimized out>, stack_end=0x7fffffffea58) at ../csu/libc-start.c:310 #11 0x00005555555b114a in _start ()

This bug is unreproducible as it is missing sndfile.d and the mentioned oscillofun.flac.
