https://bugzilla.redhat.com/show_bug.cgi?id=2173510 --- Comment #1 from Petr Pisar <ppisar@xxxxxxxxxx> --- It busy-waits on this line: SDL_FreeYUVOverlay (overlay12=0x55ac9480db70) at /usr/src/debug/sdl12-compat-1.2.60-2.fc38.x86_64/src/SDL12_compat.c:7535 7535 if (overlay->overlay12 == overlay12) { in this cycle: 7530 if (overlay12) { 7531 SDL_Renderer *renderer = LockVideoRenderer(); 7532 SDL12_YUVData *hwdata = (SDL12_YUVData *) overlay12->hwdata; 7533 QueuedOverlayItem *overlay = QueuedDisplayOverlays.next; 7534 while (overlay != NULL) { 7535 if (overlay->overlay12 == overlay12) { 7536 overlay->overlay12 = NULL; /* don't try to draw this later. */ 7537 } 7538 } The variables look like this: (gdb) p *overlay $4 = {overlay12 = 0x0, dstrect12 = {x = 0, y = 0, w = 100, h = 100}, next = 0x0} (gdb) p *overlay12 $5 = {format = 1448433993, w = 200, h = 220, planes = 3, pitches = 0x55ac9480dbd8, pixels = 0x0, hwfuncs = 0x1, hwdata = 0x55ac9480dba8, hw_overlay = 1, UnusedBits = 0} It looks like a logic bug in the code: "overlay" variable is never nulled in that cycle, thus the cycle never terminates. Maybe it should have been of a register storage and updated by a different thread/process. -- You are receiving this mail because: You are on the CC list for the bug. https://bugzilla.redhat.com/show_bug.cgi?id=2173510 _______________________________________________ perl-devel mailing list -- perl-devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to perl-devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/perl-devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
