Today it happened again with a newer Emacs, showing the same effects:
XftCharIndex(0xcd8b200, 0xcac8b80, 32, 786432, 8) = 411
XftGlyphExtents(0xcd8b200, 0xcac8b80, 0xbf9fe14c, 1, 0xbf9fdfa8) = 0
memmove(0xbf9fdfa8, 0xfa68e18, 72, 0xbf9fdffc, 0xbf9fe000) = 0xbf9fdfa8
memmove(0xbf9fde08, 0xf3cc098, 72, 12, 0xbf9fde08) = 0xbf9fde08

__ctype_tolower_loc() = 0xb70c6b14
__ctype_tolower_loc() = 0xb70c6b14
__ctype_tolower_loc() = 0xb70c6b14
XftCharIndex(0xcd8b200, 0xcac8b80, 106, 0xfe02c34, 1216) = 323
XftGlyphExtents(0xcd8b200, 0xcac8b80, 0xbf9fe14c, 1, 0xbf9fdfa8) = 0
XftCharIndex(0xcd8b200, 0xcac8b80, 112, 786432, 8) = 319
XftGlyphExtents(0xcd8b200, 0xcac8b80, 0xbf9fe14c, 1, 0xbf9fdfa8) = 0
XftCharIndex(0xcd8b200, 0xcac8b80, 97, 786432, 8) = 673
XftGlyphExtents(0xcd8b200, 0xcac8b80, 0xbf9fe14c, 1, 0xbf9fdfa8) = 0
XftCharIndex(0xcd8b200, 0xcac8b80, 95, 786432, 8) = 662
XftGlyphExtents(0xcd8b200, 0xcac8b80, 0xbf9fe14c, 1, 0xbf9fdfa8) = 0
XftCharIndex(0xcd8b200, 0xcac8b80, 121, 786432, 8) = 325
XftGlyphExtents(0xcd8b200, 0xcac8b80, 0xbf9fe14c, 1, 0xbf9fdfa8) = 0
XftCharIndex(0xcd8b200, 0xcac8b80, 95, 786432, 8) = 662
XftGlyphExtents(0xcd8b200, 0xcac8b80, 0xbf9fe14c, 1, 0xbf9fdfa8) = 0
XftCharIndex(0xcd8b200, 0xcac8b80, 99, 786432, 8) = 682
XftGlyphExtents(0xcd8b200, 0xcac8b80, 0xbf9fe14c, 1, 0xbf9fdfa8) = 0
strlen("font for") = 8
memmove(0x10931b5c, 0x823e60f, 8, 0xbf9fe0b4, 9712) = 0x10931b5c
XftCharExists(0xcd8b200, 0xd338dc8, 237, 0xce8c450, 0xff33570) = 1
XftCharIndex(0xcd8b200, 0xd338dc8, 237, 0x8225671, 0xf165965) = 432
XftGlyphExtents(0xcd8b200, 0xd338dc8, 0xbf9fe14c, 1, 0xbf9fdfa8) = 0
XftCharIndex(0xcd8b200, 0xcac8b80, 97, 786432, 8) = 673
XftGlyphExtents(0xcd8b200, 0xcac8b80, 0xbf9fe14c, 1, 0xbf9fdfa8) = 0
XftCharIndex(0xcd8b200, 0xcac8b80, 32, 0xfe02b8c, 1228) = 411
Notice the "font for" string; that may be meaningful.
After waiting around 3 minutes, I saw a round of fast free() calls for a while:
free(0x10f5e230) = <void>
free(0x10f5e330) = <void>
free(0x10f5e1d0) = <void>
free(0x10f5e210) = <void>
free(0x10f5e170) = <void>
free(0x10f5e270) = <void>
…
Then it started again, and so on:
XftGlyphExtents(0xcd8b200, 0xcaf00c8, 0xbf9fc54c, 1, 0xbf9fc3a8) = 0
XftCharIndex(0xcd8b200, 0xcaf00c8, 102, 786432, 8) = 314
XftGlyphExtents(0xcd8b200, 0xcaf00c8, 0xbf9fc54c, 1, 0xbf9fc3a8) = 0
XftCharIndex(0xcd8b200, 0xcaf00c8, 101, 786432, 8) = 313
XftGlyphExtents(0xcd8b200, 0xcaf00c8, 0xbf9fc54c, 1, 0xbf9fc3a8) = 0
XftCharIndex(0xcd8b200, 0xcaf00c8, 114, 786432, 8) = 326
…
The backtrace showed the first time:
