Hi, XEmacs 21.2-b42 gets hung in "compilation" buffer, not even c-g can interrupt it. This usually occurs after hours of use. Here's stack trace: tonyl＠magic> /usr/proc/bin/pstack 14548: xemacs-21.2-b42 fee15dd0 poll (ffbec7f8, 1, ffffffff) fedce794 select (ffbec800, fee36abc, fee36abc, fee36ac0, fee36ac0, 17) + 298 fefcd2c8 _XWaitForReadable (1902800, 1, 16, 400000, fee33a30, fee18208) + e0 fef9b45c _XReadPad (1902800, 2e703d0, 20, 2e6c4a8, ffffffff, 1ca2) + 150 fef9a288 XGetWindowProperty (1902800, 2e703cf, ffbecb5c, 2e703cf, 2e703cf, 0) + 174 00156c18 x_frame_iconified_p (16a4a00, 0, 16ea900, 50, 1, 245400) + 98 000d0ba4 Fframe_iconified_p (278804, 16a4a00, 247000, ffbecba8, 247000, 1) + 40 00153d0c handle_map_event (16a4a00, df2100, 7, 0, 38, 16a4a00) + 30 000abbd0 Fsit_for (241000, 278804, 247058, 24d400, 247000, 37) + 2bc 00065184 Fcommand_loop_1 (35, 247000, 0, 110df0c, 2, 28a018) + 164 0007f234 condition_case_1 (23a400, 247000, 245400, 64a00, 278804, 1) + 110 00064b04 command_loop_3 (247058, ffbecf04, 4, ffbecf08, 37bbd8, 0) + 48 00064b38 command_loop_2 (278804, 245400, 532200, 278804, 278804, 532200) + 4 0010b4a4 Fread_minibuffer_internal (33, 6c1744, 247000, 247800, 245000, 0) + b8 00082414 Ffuncall (240e54, ffbed07c, 1, ffbed080, 22f1b0, 1) + 2ec 0005b658 execute_optimized_program (397950, a, 24d918, 247058, 33, ffbed113) + 2cc 0005ef38 Fbyte_code (38acd4, 397940, ffbed100, 2, 297a2c, 2aa800) + f0 00081c30 Feval (278804, 247058, 245710, 229e7c, 3, 3) + 5a4 0007ee90 internal_catch (29184c, 8168c, 399730, 0, 294, 144f7c) + b0 0005ca2c execute_rare_opcode (ffbed3f4, 247000, 8d, 24d800, 33, 247000) + cc 0005b460 execute_optimized_program (369410, 8, 24d918, 247058, 23, fc1961) + d4 0005afb0 funcall_compiled_function (24d918, 240c6c, 247058, 24d444, 246800, 1) + 258 0008256c Ffuncall (240e54, ffbed59c, 7, ffbed5a0, 394c2c, 1) + 444 0005b658 execute_optimized_program (39a890, 3, 24d918, 247058, 17, 2a77dd) + 2cc 0005afb0 funcall_compiled_function (24d918, 240c6c, 247058, 24d444, 246800, 138dce4) + 258 0008256c Ffuncall (240e54, ffbed74c, 7, ffbed750, 3a0890, 129fe9c) + 444 0005b658 execute_optimized_program (39a790, 6, 24d918, 247058, 10, d9c3e9) + 2cc 0005afb0 funcall_compiled_function (24d918, 240c6c, 247058, 24d444, 246800, 5) + 258 0008256c Ffuncall (240e54, ffbed8fc, 7, ffbed900, 3a0900, 141946c) + 444 0005b658 execute_optimized_program (39a710, 15, 24d918, 247058, 9, d9c3b4) + 2cc 0005afb0 funcall_compiled_function (24d918, 240c6c, 247058, 24d444, 246800, 1) + 258 0008256c Ffuncall (240e54, ffbedab4, 4, ffbedab8, 3a091c, 247000) + 444 0005b658 execute_optimized_program (afc650, 5, 24d918, 247058, 2, 138dce4) + 2cc 0005afb0 funcall_compiled_function (24d918, 240c6c, 247058, 24d444, 246800, 5b89af) + 258 00081ee0 Feval (278804, 247058, 245710, ffbedbb8, 1, ffbedbbc) + 854 0005f790 Fcall_interactively (247058, 245400, 26d800, 575, 278804, 0) + 314 00081050 Fcommand_execute (0, 278804, 240c00, 278804, e6a138, 278804) + 194 000ad25c execute_command_event (50ca80, 241c34, 247058, 245400, 4d3f80, 0) + 1dc 000ad878 Fdispatch_event (14, 153d574, 247058, 50ca80, 4d3f80, 0) + 458 000651c4 Fcommand_loop_1 (247000, 247000, 0, 278804, 2, 28a054) + 1a4 0007f234 condition_case_1 (23a400, 247000, 245400, 64a00, 278804, 0) + 110 00064b04 command_loop_3 (247058, ffbee1b0, 245400, 64a00, 278804, 0) + 48 00064b38 command_loop_2 (278804, 64b34, ffbee258, ffbee1d8, 32, ffbee31d) + 4 0007ee90 internal_catch (28c0c4, 64b34, 278804, 0, 0, 0) + b0 00064d10 initial_command_loop (2451bc, 247058, 245400, 46693c, 2ca514, 2c7924) + 1c0 0007bb08 xemacs_21_2_b42_sparc_sun_solaris2_6 (1, 278804, 26dc00, 245000, 26dc00, ffbee41c) + 112c 0007c318 main (1, ffbee41c, ffbee424, 229800, 0, 0) + b8 0004e424 _start (0, 0, 0, 0, 0, 0) + dc uname -a: SunOS concept 5.6 Generic_105181-23 sun4u sparc SUNW,Ultra-Enterprise ./configure '--prefix=/home/tonyl/loc' '--with-prefix=no' '--with-gcc=no' '--cflags=-v -xO3' '--with-x' '--with-xpm' '--x-includes=/net/pkg/export/pkg.sparc.sunos5/X11R6.4/include:/usr/openwin/include:/import/dream/tools/include' '--site-includes=/import/dream/tools/include /usr/dt/include /net/pkg/export/pkg.sparc.sunos5/local/include/db' '--x-libraries=/usr/openwin/lib' '--site-libraries=/usr/lib /usr/lib /import/dream/tools/lib /import/dream/tools/lib/X11 /usr/dt/lib /net/pkg/export/pkg.sparc.sunos5/local/lib' '--with-database=berkdb,dbm' '--with-png' '--with-jpeg' '--with-tooltalk' '--with-workshop' '--with-cde' '--with-sparcworks=yes' '--with-xface' '--with-socks=no' '--with-mule=no' '--with-xfs=no' '--external-widget' '--site-runtime-libraries=/usr/ccs/lib:/import/dream/tools/lib:/import/dream/tools/lib/X11:/usr/dt/lib:/usr/openwin/lib' '--error-checking=none' '--debug=yes' XEmacs 21.2-b42 "Poseidon" configured for `sparc-sun-solaris2.6'.
